Extracting Gold HowStuffWorks

How Gold Works. 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 carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank,

Thioureathiocyanate leaching system for gold

Increasing the pH value does not affect the gold leaching rate significantly for the mixed lixiviant system. What is observed is the gold leaching rate for pH 1.5 is a little higher than that for pH 1.0 and 1.9. In the thiourea only solution, a high pH value is favorable for gold dissolution (Li and Miller, 2007).
