time of gold ore process

Gold extraction

A quot;refractoryquot; gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold.

Gold Smelting Process Sciencing

Gold ore extracted from mines in the earth contains a significant amount of impurities, including traces of other metals. In order to separate the gold from other metals, chemicals such as cyanide solution or mercury are introduced to the gold. This process causes the gold to coagulate, and form nuggets and clumps of gold.

Extracting Gold HowStuffWorks

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
