Process of electrowinning of gold, also called electric extraction, is a process of recovering gold by desorption electrolysis of gold loaded carbon under high temperature and high pressure conditions. It is an important part in the gold cyanidation process. Why is this process widely used in mineral processing plants?
As a precious metal, gold is commonly used in money, store of value, jewelry and art. Gold method also has a lot of, among them with immersion method and the carbon paste method is relatively common, the two methods using carbon adsorption process, the gold activated carbon is added to pulp, pulp in the gold adsorption onto activated carbon, the formation of gold charcoal, different lies in ...
Gold Leaching Process. The 700tpd gold vat leaching plant adopt the process: ore crushing and washing + pool leaching absorption + activated carbon acid washing regeneration + smelting. The mainly used machines of the project are hammer crusher, trommel, agent agitation tank, carbon adsorption column, desorption electrolysis system, pickling tank, cone agitation tank and high frequency gold melting furnace.
The integrated operation with Prominer Shanghai uses a mixture of sodium cyanide and sodium hydroxide to perform high temperature desorption and electrolysis of gold in gold loaded carbon. First, the wood chips and other debris are removed by the elutriator, and then the gold is desorbed at 150 degrees Celsius and 0.5Mpa by the high temperature ...
Desorption electrolysis system obtains gold mud from carbon by desorption and electrowinning. More gold mining equipment for gold extraction process:
Desorption Electrolysis System principle. In gold electrowinning process,when the electrolysis equipment is added with anions that are more easily absorbed by activated carbons, Au（CN）2ˉ is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution processes the via ionization.
The desorption method is to use a 1% sodium hydroxide solution and a 0.1% sodium cyanide mixed solution to heat to 90 95 ° C, the gold and silver on the gold loaded charcoal are desorbed during mixed solution pass through the gold bearing carbon layer at a certain speed.
AIMS Gold elution plant is a mineral processing plant project, located in Mwanza, Tanzania. It ...
