Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .

The cyanide solution percolates through the ore and dissolves the gold, which is then removed from the lixiviant by adsorption onto carbon or resins. Grain size, oxygen and alkalinity levels are carefully controlled to ensure maximum gold recovery. Heap Leaching. Heap leaching facilitates the profitable extraction of gold from very low grade ore.

In the late 1800s, cyanide started to be used to concentrate and capture gold from ore in a similar process to the mercury extraction, but is more efficient and loses less gold to the tailings. Once the rock is pulverized, it is mixed with water to create a slurry and a cyanide solution is added.

Process of Cyanide Gold Extraction. Pachuca aeration gave better gold extraction and lower cyanide consumption than bottle agitation. With the former more copper was found in solution, and less thiocyanate was formed; with bottle agitation the reverse was the case, in addition to which copper cyanogen complexes were found in the filter cake.
