In this study, potassium hydroxide leaching as pretreatment before cyanide leaching of a flotation concentrate of an antimonial refractory gold silver ore was investigated. The ore assaying 1157 g/t Ag and 3.96 g/t Au was found to be composed of predominantly quartz, barite, kaolinite, clay, mica/chlorite, and dolomite/ankerite.
2. Froth Flotation + Concentrate Thiourea Leaching. For vein gold ore with high arsenic and sulfur or high carbon argillaceous, the gold sulfide concentrate can be obtained by the froth flotation, and then the flotation concentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly ...
Froth flotation is an important concentration process that can be used to selectively separate hydrophobic materials from hydrophilic waste gangue. In a more simple context, froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially ...
The industrial flotation method of jamesonite also adopts froth flotation. In addition, jamesonite is associated with valuable metals such as antimony , lead , zinc , silver , indium and bismuth , which can be used as raw material to extract these precious metals, and has a high economic value.
Therefore, flotation and leaching, both of which are the first stage of each scenario, of finely ground ores are of crucial importance to assure the continued supply of metals. This Special Issue will be devoted to collecting papers on recent advances in selective flotation and leaching processes for any metal containing ores.
