Electrowinning Mercury in Gold Pregnant Solution
Gold extraction ranged between 0 and 20 pct. Results of the investigation showed that choice of hode material was critical to the success of the process. Selectivity was not achieved using uncoated steel wool hodes. A large number of lowgrade gold and silver ore deposits are now being mined and milled throughout the Western United States.
pH/ORP measurement Cyanide leaching process
The carbon captures the dissolved precious metal in solution through a mass transfer process known as adsorption. The carbon moves countercurrent to the pulp flow so that the new carbon contacts with the lowest concentration of goldbearing solution in the final CIP tank. The plant removes the loaded carbon at the first CIP tank
Major Mines and Projects Jundee Mine
The cyclone overflow slurry reports to the carboninleach circuit for the processing of nongravity recoverable gold. The circuit comprises two leach tanks and six adsorption tanks where the gold is leached into a solution and adsorbed onto carbon. Carbon containing adsorbed gold is referred to as loaded carbon.
