June 19, 2010: The National Gem and Jewellery Authority recently revealed that gold can be produced by further filtering black sand. “We disclosed that many valuable metals exist in the sand that is removed from gem mines. We had difficulties in filtering and identifying these metals as we did not have the necessary equipment in the country. But one of our own entrepreneurs has invented this machine.” said the Chairman of National Gem and Jewelllery Authority Anil Koswatte. Meanwhile, Ananda Samarathunga, the inventor of the machine which filters gold from the black sand, noted that he had found this while using the machine to sift black sand for gems. “While using the machine to sift black sand for gems, I saw it being cleaned and filtered. So I invented a machine to do this. After separating the black sand, I noted that there are traces of gold in it. Now we have the ability to separate the gold from It,” said Samarathunga. According to the Authority, there is a possibility of producing gold locally at a cost 40 per cent chapter than importing it. It has already been established that the gold processed in this manner is 23.35 carrot pure gold. Meanwhile, the National Gem and Jewellery Authority noted that many other valuable metals including Titanium and Uranium could be produced in the same manner. According to the Chairman of the Authority, a tonne of black sand can be sold at a price of around US $ 10000 overseas.

Using an underwater metal detector doesn’t require you to be a master scuba diver, because any stretch of where a river is too wide to dam or divert that runs more than four feet of water year round is almost certainly virgin or near virgin territory. However, if you are already a scuba diver it allows you to really get into unexplored territory with underwater metal detectors like this Minelab Excalibur II.
In the eastern United States, placer deposits have been discovered in streams draining the southern Appalachian region in Maryland, Virginia, North Carolina, South Carolina, Georgia, and Alabama, and these often deeper streams and rivers are great areas for the use of underwater metal detectors.

I recently sold a tin that contained candies, which I bought about a month ago. I sold it to a woman who paid 10 dollars for it because she was collecting tins from this particular brand of candy and my one had a famous cartoon character on the side of it. On one particular night I was getting rather bored and actually took a rest on the sand whilst the others continued detecting. Whilst sitting in the sand I started sifting with my hands and out popped a 24 carat gold necklace. I was hooked.
When you think of treasure hunting, maybe gold coins and precious stones come to mind, but it doesn’t end there. You can start in your own attic to see what treasures you find. Then you can check out some of the more unusual ways to go treasure hunting. The bottom line is that if you want to take up the hobby to purely make money – the odds are against you. If you want to take a hobby and meet all interesting people, go on digs or dives together, have frills of finding Gold and Silver, Old and New…………..with the chance of finding that one off find, then join the hobby. It has a lot to offer.
Several years ago, I treasure-mapped a trip to California. My husband and I were newly weds with debts from former marriages. There was no way that I could purchase the air-fare to California. After I treasure-mapped my trip, I actually won a contest and received the round trip ticket to California in the mail!
Who Else Wants to Know About Some Accessories in Metal Detecting?
Metal detectors are not an all-for-one device. This means that metal detectors cannot exist alone. They need some metal detecting accessories to facilitate or expedite the detection process. If you want to pursue your dream as a treasure hunter or you simply adore finding rare and valuable metals hidden beneath the earth’s surface, investing in a good set of metal detectors and accessories for metal detecting is important. This will guarantee your search will be more positive and more valuable findings.
However, not all accessories in metal detecting are the same. Hence, it is important that you know these items so that you can easily identify them as you encounter them in the market.
1. Books about metal detecting
You need to have a wide array of good metal detecting books. Experts say that nearly 90% of successful people in metal detecting are well adept and knowledgeable of the process. Hence, they say that one of the most important tools in order to succeed in metal detecting is knowledge. And you can only gain it through metal detecting books and experience.
2. Digging tools
To treasure-map a spouse or special companion, concentrate on finding pictures that represent what you want the relationship to look like: how you want to be treated, what you will do together what values you would share, etc.
Although you may not realize it, metaphorically the Publishers Clearing House comes by your door every morning, and every day you have the winning lottery ticket. How is this possible? Well, within you there already exists a treasure chest. It is filled with the priceless jewels of your own positive memories and your capacities to achieve positive states of being.
Walk-through metal detectors are most common in airports, hotels, government buildings, and other public places. They are designed to detect razor blades, weapons and microprocessor chips. They come with superb discrimination, excellent target selection, high throughput, low false alarm rate, uniform detection within the entire archway, and a bi-directional system.
Our city collects large junk for free during a week each spring. We see good bicycles, furniture, games, toys, chairs, and more, in front of almost every house. Several people come with trucks and trailers to pick out things to sell at flea markets or auctions. It’s a regular source of income for some of them. I’m sure this happens in other cities too.
Corporate teams will spend the entire day in wandering to every possible locations and comparing the sites with the given photographs. In this event, each team has to take photographs, which should be similar to the given photographs. You need these tools to retrieve your metal detecting finds, such as nuggets, coins, relics, and jewelry items. Never use your bare hands or any other tools not created for digging. You may only damage your metal detecting finds.
3. Harness
To lighten up the burden of carrying your metal detector, try using a harness. You can find a good harness for every type of metal detector.
4. Plug popper
In order to retrieve rings and coins without denting or scratching the turf, try to use a plug popper. This will enable you to remove clogged coins or any metal detecting finds without having to damage your turf.
5. Sand baskets
If you are into beach metal detecting, it is best that you have sand baskets to facilitate the process. Since the sand is made of very tiny particles, it will be hard to find coins beneath the layers. Hence, to retrieve jewelry and coins easily and fast, try to use a sand basket
6. Headphones
You need these items to enable you to hear even the faintest sound of a target. With them you will never miss a find, so have a good set of headphones with you. All of these things are specially built to expedite your metal detecting process. You can never start your metal detecting activity without these items. Otherwise, you have to settle for alternatives, which create a greater risk of damaging your finds or your metal detector device.
Get ready for the hunt of the season. If you have an energetic and adventurous corporate team with a limited budget, then GSP treasure hunt in Derbyshire is just the right thing for you.
Even with the best scoops available, it is sometimes very difficult and frustrating to try to recover targets at the edge of the surf. Find out more about metal detectors at metal detector info site. But there are plenty of things people have overlooked that with some time and imagination can be objects of beauty in your home.
Americans treasure their past, which is one reason antiques are so popular. Antiques are relics of a time now gone. We look back on our history with pride. Furniture, jewelry, even automobiles that were in common use many years ago, are prized antiques today, simply because of the era they came from.
You might find iron debris, broken potteries and glassware which could be the best location to find older items and perhaps even novelty coins, jewelries, watches, relics and other possible collectibles. Go where people gather together during the busy season, local beaches, town beaches, old marinas, and ocean beaches are most likely the prime spot for buttons, bullets, sinkers, Indian artifacts, old charms, and ornaments.

Metal Detecting in the UK
Metal detecting is a hobby that is not just popular in the United States. In the United Kingdom, metal detecting is also a rather popular activity enjoyed by many. Clubs, organizations and groups abound, along with many popular locations that are perfect for metal detecting enthusiasts.
Metal detecting actually has a long and rich history in the United Kingdom. Interestingly enough, the invention of metal detectors sprung not from a recreational or leisurely need: on the contrary, it came from the need to detect the locations of dangerous mines, so that they might be disarmed. By the end of the Second World War, metal detectors had become considerably sophisticated and effective. Soon after, some archaeologists began using mine detectors in their digs and excavations, in search for ancient metal artifacts.
By the 1950s, metal detectors began to be used to recover small items like coins in England. The brothers Caiger-Smith used what were previously mine detectors to recover modern as well as Roman coins in the fields surrounding the town where they lived, in the Newbury area. They even wrote and published their experience with metal detectors and what these nifty gadgets could possibly accomplish in the future. The paper sparked interest in metal detectors that would continue to grow until the present time.
Go to your local ” do it yourself ” coin operated car wash. Look for the place where they dump the contents of the 25 cent vacuum cleaners. Search the piles and see what a gold mine they are for coins and rings. Any place there is construction and the ground is being cleared, that is a great place to start treasure hunting. Successfull treasure hunting starts with having the right metal detector. But which type of metal detector should you get? Complete info on metal detectors and treasure hunting at detect-metal.info.
ome detectors have more ways of adjusting the “fit” to the person. Some of the other ways that detectors adjust are that the arm cup can be raised or lowered, and the box containing the board and controls can be taken off of the pole and mounted in a small pouch. Many people say to us “I have always wanted to do this!” As with other electronic equipments, innovations seems to always happen overnight. If you are going to buy a metal detector today, try to know that technologies are currently employed. You do not want to be behind the technology line, right?
If you are planning to buy a metal detector, you should check out the features of each before buying one. Metal detecting is a fun hobby but having the wrong equipment can cost you time and money. Mention the words metal detector and you’ll get completely different reactions from different people. For instance, some people think of combing a beach in search of coins or buried treasure.
As in most other countries, laws govern metal detecting in the UK. A metal detecting enthusiast should be granted permission to go metal detecting on all lands except those that are open to the public such as parks and beaches that are not privately-owned. Otherwise, in the case of fields and farms that are privately owned, you must ask permission first before you search, and usually an agreement between the property owner and the metal detecting enthusiast is made regarding any items of value that may be found in the area.
There is also a Treasure Act and Code of Practice in the UK that every metal detecting enthusiast should read and remember; as there are certain items, such as coins that are older than three hundred years old, that must be reported to the authorities when they are found. Metal detecting is so popular in the United Kingdom that a national body has been set up for the hobby. The national body is called the National Council for Metal Detecting, or NCMD, and you can visit their site on http://www.ncmd.co.uk, where you can find some very useful information on metal detecting in the UK. A recent study proves that hand-held metal detectors are just as accurate as x-rays in finding coins and other metallic objects swallowed by children.
Now that you have learned the three different types of metal detector, itos up to you to make your choice as to what type of detector you wish to use for your searches.
Some users put a rubber band around the knobs to keep them from moving or becoming loose. You should buy a metal detector that is light weight. This is important when you are detecting things on a riverbank or body of water.
The Garrett Enforcer G-2 is the smallest body scanner and sensitive enough to detect even the smallest of knives or guns.
The most popular one is the Super Scanner. It can detect hatpins as small as one inch.

OK, some of my readers seem to believe that the documents I post are to obtuse for the average weekend gold miner. I don’t tend to agree because the average weekend gold miner is probably an engineer, auto mechanic, or school teacher during the week, and none of this stuff is rocket science. Also, you know that the weekend gold miners are smart, because they aren’t wasting there time playing golf.
Well, the document that I am posting this week placer-mining-california-doc-division-of-mines-and-geology is one that should be useful to almost every weekend gold miner whether you live in California or not.
This document is a very detailed thirty-seven page report on placer mining and from reading it you could pretty well go out and start washing dirt. It has plans for sluice boxes and lot of other cool stuff.
The precious metal of gold has fascinated humans for thousands of years. But how do we actually get it out of the ground? Let’s take a look at the most common ways to mine gold.
There are two main gold mining methods, one is called “placer” and the other is “vein” mining. And another type of mining is when gold is collected as a by-product in the mining of other metals.
Placer Mining
Placer mining is practiced when the metal is found in unconsolidated deposits of sand and gravel from which the gold can be easily separated because of its high density. The sand and gravel suspended in moving water. Much heavier metal sinks to bottom and is separated by hand.
The simplest method of placer mining is panning. Here the miner swirls the mixture in a pan rapidly enough to carry the water and most of the gravel and sand over the edge while the gold remains on bottom. This was the classic method used by the Forty-Niners during the California gold rush of 1849 and has been immortalized in story, art, and song.
A more efficient form of placer mining uses a sluice box, a U-shaped trough with a gentle slope and transverse bars firmly attached to the trough bottom.
The bars — extending from side to side — catch the heaviest particles and prevent them from washing down the slope.
Sand and gravel are placed in the high end, the gate to a water supply is opened, and the lighter material is washed through the sluice box and out the lower end. The materials are caught behind the bars and are gleaned to recover gold.
Another variation of placer mining is called hydraulic mining. A very strong stream of water is directed at natural sand and gravel banks washing away the lighter materials. The suspended materials treated as if they were in giant sluice box.
Currently the most important placer technique is dredging. A huge shovel of several cubic meters capacity lifts the unconsolidated sand and gravel from soil and mud and the placer process starts.
Vein Mining
Vein, or lode mining is the most important of gold recovery methods. Each ounce of gold recovered requires the processing of about 100,000 ounces of ore. Much gold is deposited in rock veins and this method accounts for more than half world’s total gold production. Gold in veins may be of microscopic particle size, in nuggets or sheets, or in gold compounds. The ore requires extensive extraction and refining.
One-third of all gold is produced as a by-product of copper, lead, and zinc production. Copper must be electrolytically refined to raise its purity from 99% to the more than 99.99% that is required for many industrial purposes.
In the refining process an anode of impure copper is electrolyzed in a bath in which the cathode is a very thin sheet of highly refined copper. This process
creates anode sludge which contains gold in quantities sufficient to make its recovery profitable. One-third of all gold is obtained from such by-products.
Silver and platinum are also recovered from the copper anode sludge in quantities large enough to more than pay for the total refining process.
Extraction, Refining and Uses of Gold
Ore from the gold mine is first crushed in rod or ball mills. This process reduces the ore to a powdery substance. The gold is then extracted by amalgamation with mercury or by placer procedures. Approx. 70% is recovered at this point.
The remainder is then dissolved in dilute solutions of sodium cyanide or calcium cyanide. The addition of metallic zinc to these solutions causes metallic gold to precipitate. This precipitate is refined by smelting and the purification is completed by electrolysis. The sludge produced in this process will also contain commercial quantities of silver, platinum, osmium, and other rare-earth metals.
Gold is one of the first two or three metals, along with copper and silver that was used by humans in these metals’ elemental states. Because of its poor chemical reactivity it was found uncombined and required no knowledge of refining. Gold was used in decorative arts before 9000 BC. And civilizations prized gold for its beauty.
A principal use of gold today is as a currency reserve. For centuries gold was used directly as currency along with silver. During the 19th century, gold assumed the role as the sole basis of the currencies of most nations. Paper money was directly convertible into gold.
World War I, however, disrupted the “gold-standard” system. The original gold standard was gradually abandoned. The United States stopped minting gold coinage in 1934 and the dollar eventually emerged as the principal unit of international monetary transactions.
Since the 1970s, gold has been bought and sold on the world market, with widely fluctuating prices. Today gold reserves maintain only a very indirect relationship with currency values. However, as gold has declined as a currency reserve, its use in industrial processes has risen. On top of this, its beauty and workability continue to give gold an important role in the world’s jewelry industry.

Gold Mining On The Yuba River The Ancient American River, Ancient Yuba River, Ancient Calaveras River, Ancient Mokelumne River, Ancient Tuolumne River, Ancient Magalia Channel, Ancient Intervolcanic Cateract Channel, Ancient Intervolcanic American River and the Ancient Jura River (from the Jurassic Period), are plotted in detail on Big Tens California Gold Map 5. The present-day rivers bearing the same names as their ancient rivers are also shown. The Ancient Rivers of Gold in northern California are from the Tertiary Period. The Tertiary rivers existed millions of years ago and many of them had large quantities of gold within their gravels. Because of that, they are known as the “Ancient Rivers of Gold.” Each ancient river is discussed below. Information on this page is based on the classic work of Waldemar Lindgren of the United States Geological Survey and by study of Big Tens California Gold Map 5, which shows the relationship of the ancient rivers to landmarks, such as roads, creeks and towns in the region. These now-dry Tertiary rivers are thought to be a prime source of the gold found in many of the rivers and streams of the Mother Lode region of northern California. The ancient rivers are discontinuous and sometimes follow tortuous routes. They have been altered by volcanic activity, erosion, and in some instances portions of the rivers have been covered by lava. Much of the region underwent extreme volcanic eruptions. Volcanic flows have been found up to 4000 …
