Аннотация

As a result of studying the size of gold particles, it was found that the ores of the Gedabek deposit contain both finely dispersed and coarser gold. Finely dispersed gold is extracted from ores by heap leaching, and coarser gold by flatation. When studying polished sections, it was found that free and bound gold is associated with the surrounding sulfide minerals - pyrite, chalcopyrite, arsenopyrite. In the Gyzylbulag deposit, the size of gold is larger - 0.015-0.02 mm. Such gold is extracted from ores by the method of flatation and gravity. The deposit contains quartz-pyrite-chalcopyrite, quartz-chalcopyrite and chalcopyrite-sphalerite mineral associations. Of these, quartz-chalcopyrite is more productive for gold. The Goshinsky gold deposit is usually found in early pyrite in a finely dispersed state (0.001-0.1 mm) and is extracted from ores by agitation cyanidation. Dagkesaman deposit gold size varies within 0.001-0.025 mm extraction of gold from pyrite-polymetallic ores by gravity.
