Extremely fine-grained (or "") gold occurs in sand deposits along the Snake River in southern Idaho. Colorado Placer Deposits Placers in Colorado have been mined in the Fairplay district in Park County, and in the Breckenridge district in Summit County. In both areas large dredges were used during the peak activity in the 1930's.

The purpose of the washing operation is to separate the sand from granular soil, and to clean the fine mud adhering to the gravel and mix the gold particles in it. The commonly used washing machine is spiral classifier. Then the washed sand is fed into screen for further process. Generally, there is no gold contained in large gravel.

When a valuable lode is found, in order to mine it, the ore is usually blasted out of the vein and is crushed down into a very fine powder from which the gold, silver and/or other valuable minerals can be extracted by any number of chemical or mechanical procedures. This entire process is called "lode mining" or "hardrock mining".

There are two basic steps to gold mining: prospecting and production. "Prospecting" refers to the actual search in a certain area for valuable minerals, and "production," also known as mining, is the physical act of removing the gold from where you found it.

Which works out fine, since all the gold mines in Big Rock were squeezed dry years ago. Even so, that won't stop a pair of businessmen from the East from trying to squeeze out a little more. One of them has developed a newfangled method for extracting gold—something called "hydraulics" and they've bought up all the old mines to do it.

But if the gold price rises by 20% to $1,200 the mine will make $400,000,000 overall. This demonstrates a 'gearing' effect of 4 times - i.e. for a rise in bullion of 20% the share will rise by the 20% plus another 4 times 20%, i.e. 100% (all other things being equal, which they rarely are).

How Mercury Is Used in Gold Mining . First, mercury is mixed with the materials containing gold. A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold.
