“…In the work, it was established that with the help of fine and ultrafine grinding, the required completeness of the disclosure of intergrowths of sulfide minerals with each other and host rocks is achieved in comparison with traditional ball grinding, and hydropercussivecavitational grinding increases the selectivity of the opening of intergrowths with the equality of the granulometric composition of the grinding products of rotary-pulsation apparatuses and ball mills [8].…”

The task of the tests was to study the material composition in order to develop a rational technology for the enrichment of porphyry copper balance and off-balance ores of the Yoshlik I and Kalmakyr deposits to obtain collective, copper- and molybdenum-containing concentrates, finished products in the form of copper, molybdenum and pyrite concentrates. The material composition of ore samples was studied using spectral, chemical, assay, granulometric, phase, rational for gold and silver, mineralogical, and other types of analyses. Due to the absence of significant bonds of gold with pyrite, there is no expediency to carry out extensive studies of the hydrometallurgical processing of pyrite concentrates. It is possible to set up a basic experiment to determine the proportion of cyanidated gold. When processing ore raw materials enriched by flotation, not only various flotation reagents-collectors, technological parameters, but also the grinding size and material composition of the ore are important for obtaining a concentrate, since grinding the ore to the required size is about half the cost of obtaining a concentrate.

“…Studies in the field of ore preparation revealed that the impact (dynamic) method of destruction is the most rational for the preliminary preparation of material before beneficiation and has a number of advantages in terms of the degree of crushing, energy consumption, and most importantly, in the release of useful components. The main goal is not only to reduce the particle size of the crushed material, but also to maximize the possible release of the useful component from the ore mass, which occurs in the main mode of disintegration along the weakest intergranular and intermineral bonds of complex in texture ore polymineral natural complexes (aggregates) [8][9][10]. This phenomenon is defined in the technical literature as the selective release of certain mineral components due to the selective nature of the destruction of rocks that are complex in composition and texture.…”

The article presents the results of research on the development of processes and equipment for ore preparation and pneumatic dry beneficiation of mineral ores. The methods of crushing and grinding before enrichment of minerals have been considered, dry enrichment of geomaterials is investigated. Highly efficient prototypes of beneficiation equipment are developed and tested: crushers of multiple dynamic impact RD-MDV-900, DKD-300, centrifugal grinders CMVU-800 and VCI-12, pneumatic separator POS-2000. Fundamental designs are created, and a number of new ore preparation and pneumatic beneficiation instruments are being designed. The efficiency of approbation of an autonomous dry beneficiation complex with new safe environmental standards for the processing of gold-bearing ores, which makes it possible to fully release and extract free gold with a particle size from 10,000 to 100 µm, is shown. The introduction of the dry beneficiation method is very promising for the mining industry. It will allow to reduce capital costs for the construction of stationary beneficiation plants, completely or partially withdraw from the use of process water, the construction of a water supply system, a traditional tailing dam, etc.
