Abstract:
The Shaumian sulphidic collective polymetallic concentrate analysis is carried out by X-ray and microscopic methods, in order to estimate by its example the mineralogical structure and interrelation of minerals for this type of gold bearing copper – zinc – lead complex ores, from the point of view valuable metals recoverability. It is shown that the gold and silver are allocated mainly in sulphide grains which must be decomposed to recover the noble metals. And the some minerals are combined so closely with each other (especially, sphalerite with chalcopyrite and chalcopyrite with galena) that it is quite impossible to separate them in ordinary industrial milling and flotation conditions.
