How to profit from low grade gold mines Part 1 Kitco News

Extracting gold from ore can be complicated and countless mines have failed because they did not recover enough gold to balance input costs. The most commonly used process to extract gold is cyanide leaching, based on a chemical reaction first identified in 1894 by L. Elsner. A slurry of ground ore is mixed with cyanide in the presence of activated carbon. The carbon adheres to the gold, which
