gold beneficiation process ie carbon in pulp
A theoretical study of the carbon in pulp process for gold
The carbon in pulp process for gold recovery involves treatment with cyanide under aerobic conditions at high pH, to give the Au(CN) 2 − ion, which is then recovered by adsorption on carbon, followed by elution of the Au(CN) 2 − in caustic Gold carbon-in-pulp(CIP) is a typical gold beneficiation process for the effective recovery of gold-bearing minerals with a high oxidation degree and low grade of raw ore.

Gold Ore Beneficiation: Factors to Consider When Choosing a Process
The cyanide solution dissolves the gold, which is then collected and processed. Cyanide leaching is a controversial process due to its potential environmental impact, but it is still widely used in the gold mining industry. 4. Carbon-in-Pulp (CIP) Carbon-in-pulp is a process that involves the use of activated carbon to extract gold from ore.Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has A Review of the Cyanidation Treatment of Copper-Gold Ores
