Cyanide gold mining process will be introduced in the article.There is very few valuable mineral in gold ore which is usually concentrated after crushing and grinding. Gravity processing, flotation processing, magnetic processing and electric processing are commonly used in gold processing. Gold will be concentrated according to cyaniding. We will discuss cyanide gold mining process briefly in this article.
Cu is a physically and chemically element, which is existed in nature as simple substance except for aqua regia. KCN, the common cyaniding leaching raw material, which is referred in three theories:
4Au + 8KCN + O2 + 2H2O = 4KAu(CN)2 + 4KOH
Isner thought that KCN, dissolved oxygen, and water react with gold in water, and integrate into solution as the shape of a complex.
2Au + 4KCN+ O2+2H2O = 2KAu(CN)2+2KOH+H2O2 ,2Au + 4KCN+H2O2= 2KAu(CN)2+2KOH
This theory holds the view that gold integration into cyanide in two steps together with the processing of producing hydrogen peroxide, which has the same equation with the oxygen theory.
This theory holds the view, the gold leaching processing is an electronic corrosion processing. There is electronic current within the gold particle. So there is positive zone having positive electronics and a negative zone having negative electronics. Cyaniding leaching is the processing positive Au losing electronics and becoming the negative electronics. Dissolved oxygen obtain electronics and react with water and producing dissolved peroxide and OH.
With the developing of cyanide gold mining process research, the principle of cyaniding leaching is coming to humans. Cyanide is poisonous which will be highly harmful to the environment if they were leaching. So from the environmental perspective, we should find the replacement to reducing environmental pollution.
Nowadays, with the market demanding to change, gravity thickener price also fluctuated. Different thickener specifications have a different price. ... [more]
Ultimately technicians determined tot adopt the solution of copper lead mix-mining flotation, mixed concentrate separation of copper and lead, and zinc tailings on the basic of low copper content according to many times of mining flotation test. ... [more]
