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 .
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
The procedure is very similar to refining gold in aqua regia, but the precipitant used will be different. There are several standard precipitants, different precipitants for different platinum group metals. Refining by this method is tricky and the purity of the resultant platinum group metal is often below normal standards.
We design and manufacture systems for the gold refining by chemical means (with aqua regia or by the method of inquartation) and by electrochemical (electrolysis). Plants designed to guarantee maximum efficiency and high purity of the refined metal with minimal maintenance requirements.
