    Mercury Usage in Gold Mining and Why It Is a Problem ThoughtCo

    A mercurygold 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. This process does not result in gold that is 100 pure but it does eliminate the bulk of the impurities.

    of highgrade ore and can be acquired at a cost of 10 per ton of ore (cost of mining ore at site). A sodium cyanide process is used to extract the gold from the ore and various other processing techniques are used to produce pure gold bullion from the ore. The results of the feasibility study show that the ore can be processed by agitation
