· I have access to a large amount of "Black Sand' ore concentrate, which has assays showing extremely large concentrations of Gold, Platinum and Rhodium. But many people say it is worthless because it is "impossible" to extract the precious metals from the junk (especially Iron).
An outline of the properties of gold in including fool's gold, carats and its properties. Skip to content Gold is valuable simply because it's scarce and difficult to extract. However, gold is by no means the scarcest or even the most expensive metal. The current price of gold (October 2002 prices) is $322 per troy ounce, compared with
North Carolina: The Golden State. Before long, men found other ways to extract gold from places across North Carolina. One man started using high pressure water hoses to blast away the muddy soil that held the gold in its clutches. Miners also used black powder to blast the gold ore away from the rock. Each year, the methods
The gold mineralization is located along the breaks and subordinate splays as individual fracture fill quartz veins, from several inches thick to as much as 12 ft. thick. The Macassa Mine employs conventional drill and blast mining methods to extract the ore. Mining is by mechanized cut and fill, normal cut and fill or long hole methods
· Best Answer: A typical "rich" gold ore assays about a fifth to a tenth of an ounce of gold per ton (3 6 grams per ton). If your bag weighs, say, ten pounds (1/200 of a ton) then the amount of gold in it is probably in the order of 0.015 to 0.030 grams or at todays massive gold price about $0.40 to $0.80, assuming that you could extract
Of the 32 producers, only 17 of them have a cost lower than the current gold price. This means massive dislocation of ore and soaring environmental costs to comply. Energy costs is not a fixed cost so it has far less to do with costs of mining than before. WHAT WOULD BE APPROXIMATE INVESTMENT TO EXTRACT GOLD FROM
Idaho Maryland Mine History. The Idaho Maryland Mine, located in the Grass Valley mining district of northern California was one of the most productive and best known gold mines in the Unites States, with gold production from the property dating back to 1863.
Grinding media type, water chemistry and gold bearing sulfide ore interaction The focus of this project is to better understand the influence of grinding media on the flotation of gold bearing
Minnesota is the largest producer of iron ore and taconite in the United States. Even though nearly all of the high grade natural iron ore in Minnesota has already been mined, advances in technology have found a use for lower grade iron ore, called taconite. Silica sand is a very fine sand composed of quartz (a white to colorless mineral

The ore is mainly quartz but at the Golden Messenger the gold has been found to be associated with galena which occurs sparingly in the unoxidixed ore. Pyrite, sphalerite, and chalcocite also occur in small amounts (Sahinen 1935).
While prospecting along the Hassayampa River in October 1863, Henry Wickenburg and several associates discovered a gold bearing quartz outcrop 500
Outcrops of quartz vein matter among slabby slate rock as pictured here, is a fine geologic indicator that gold could be found nearby Know Your District The geologic concepts and indications that are the most important for finding gold vary from location to
Successful gold mining is generally done in two steps: often contained in quartz veins. "Placer" gold deposits are created after erosion has broken the gold away from the lode and deposited it elsewhere. There are different kinds of placer deposits.
