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
Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide

PHASES OF A MINING PROJECT There are different phases of a mining project, beginning with mineral ore exploration and ending with the postclosure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. Exploration

leads to the conclusion that gold actually occupies a unique position among the elements. There are several consequences of this effect in gold chemistry: 1. The color of gold. Gold has an absorption beginning at, attributed to a transition from the filled 5d .
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.
