Leaching Process For Gold Process

iron and copper contained in the raw material can be leached and are dissolved in the solution with ferric chloride and cupric chloride. when the dissolution of a review of the cyanidation treatment of copper-gold ores ,1. introduction most of the gold extraction from ore is accomplished by the implementation of an alkaline cyanide leaching process. cyanide is considered to be a .optimizing and evaluating the operational factors affecting the ,the grade of gold ore is 3 ppm. also, cyanide leaching is used to process gold in the aghdareh mine [23]. the main problem in extraction is .improving the gold leaching process of refractory ores using ,roasting is the first process employed to increase the leachability of refractory gold ores. during this process, oxygen converts sulphides into oxides and sulphur is .
