The material composition and technological characteristics of this mineral raw material characterizing the gold-quartz-sulphide formation have been considered in detail by the example of two technological samples with 1000 kg weight, selected from various natural ore types of field. The occurrence forms of main ore minerals and precious metals (Au, Ag) have been determined in appropriate ores types. It has been revealed that a significant part of gold in the investigated ore types of the field has been represented by relatively large free native grains, easily recovered by gravitational beneficiating method. Taking into account the material composition and revealed technological characteristics there have experimentally been estimated various technological schemes of mineral raw material processing providing a high degree of the complex recovery of the valuable components in the appropriate commercial products.
