In connection with the decline in the quality of reserves of many types of mineral wealth, there is a need to develop mining techniques and technologies that allow for effective development of deposits having increasingly hard mining conditions. In the ores of non-ferrous, rare and noble metals, the concentration of ore minerals in small classes of loosened ore mass is often observed. The paper analyzes the nature of the distribution of gold, tungsten, lead and some other useful components in the original ores, and presents methods for the treatment and primary processing of the ore mass with the separation of enriched classes. An engineering and technological solution has been proposed that provides an increase in production efficiency in opencast mining of deposits, the ores of which, after disintegration, are characterized by the enrichment of small classes, due to the separation of substandard ore siftings in the mine face directly during mining operations, their subsequent sorting and processing, as well as increased productivity and extended functionality of mining equipment. The use of the mining complex when excavating the rock mass will provide a reduction in the cost price, which will allow the complex-structured areas of the deposits to be involved in the development, composed of low-grade and off-balance ores.

“…To identify and extract such formations, it is necessary to use the processes that ensure the transformation of the crystal lattice of mineral concentrators with the movement of clusters of integral and defragmented particles to the surface of micro-and nanocracks, pores, and their subsequent aggregation. The implementation of this condition can be carried out both by physical action on the crystal lattice of minerals, and by chemical means: using solutions containing active components that can penetrate into its inner layers [1][2][3]. One of the directions of intensification in the processing of mineral goldbearing mixtures of various genesis is the process of mechanical activation.…”

The results of experimental studies on the use of mechanical activation in the processing of ores and anthropogenic materials of the Far Eastern region are presented. The effectiveness of the use of electrophotoactivated solutions and complex reagents at the stage of mineral preparation has been established. Technological solutions have been proposed to reduce the loss of finely dispersed and chemically bonded gold during the processing of gold-bearing materials based on a directed change in the properties of the surface of minerals. The effectiveness of the use of the mechanochemical activation process for various aspects of the technological chain has been experimentally confirmed – a decrease in the sorption properties of materials, development of microcracks in oxidized ores for the penetration of leaching solutions into mineral aggregates, oxidation of the surface of primary ores, and removal of films from the mineral surface. Indicators of technological refractoriness of the studied ores and anthropogenic materials were revealed – a high proportion of chemically bound gold with atoms of basic and accessory mineral-forming elements, the presence of grains of the valuable component covered with oxide films, enclosed in carbonates, quartz and waste rock. The refractoriness of ores is confirmed by a high sorption capacity (the predominance of carbonaceous and clay matter), the presence of trace impurities in gold (Sb, As, Cu, Fe, Hg), which increase the consumption of cyanide during leaching. The material composition is dominated by a significant amount of chemical elements – cyanosides, actively interacting with the main complexing agent of leaching solutions – cyanide of alkali metals.
