It is not economical to use the cyanide method to extract gold, and the heap leaching process has economic benefits. The heap leaching method actually deposits gold bearing ore on an impervious site and is immersed and leached with a cyanide solution. After dissolving the gold and silver in the ore, the pre designed grooves along the site flow into the storage tank. The gold silver containing

Rcovery of gold in pyritic ores Mine Engineer.Com

In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to 200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns down to 2 or 3 microns. The incidence of fine gold

Extracting Gold HowStuffWorks

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, the gold adheres to the carbon.
