Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from ores. Very few metals such as the noble metals,, Gold, Silver, and Platinum etc. are present in their original metallic forms in nature.
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.
A feasibility study on the production of gold at a fictitious mine (Moapa mine) in Elko County, Nevada is to be performed. The mine is capable of producing 325,800 tons of highgrade ore per year for 8 years. The deposit contains ounces of gold per ton of highgrade ore and can be acquired at a cost of 10 per ton of ore (cost of mining ore
