The gold ore once mined is processed by separating the gold mineral from the crude matter holding it together. The ore is then pulverized using pressure to create very fine particles. The fine particles are then heated in a furnace to temperatures over 1,064 degrees Celsius, which is the melting point of gold.

The importance of using a representative sample is highlighted by Ore 1. Although the most representative sample size had been determined for Ore 1 (see Table 3) it was found that this was too large for analysis and hence a smaller sample size of 1. kg was used resulting in significant errors.. The large sample size required for Ore 1 was …

The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press.
