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

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined To collect the gold from the ore it needs to be separated from the other minerals in the ore To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble

Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets This page offers a comparative review of gold recovery
