On an example of 10 technological tests of the various scale, which has been selected from various natural types of ores of Gosha gold-pyrite deposit, the matter compositon and technological peculiarities of mineral raw materials are considered in details. The forms of finding of the basic ore minerals and noble metals (Au, Ag) are established in corresponding types of ores. It is revealed that the basic part of native gold both in initial and in oxidized ores is presented by small, sometimes thin-dispersed grains concluded in ore and nonmetallic minerals. Thus, the close association of gold with silver and bismuth tellurides is typical for initial ores, confined to pyrite, but the basic concentrator of gold is goethite in oxidized ores. The technological indicators received on various methods of given mineral raw materials processing are considered here.
