The conducted scientific work is aimed at studying the acute problem in the field of ore minerals processing. The most energy-intensive and expensive process in the extraction and beneficiation of mineral raw materials is their destruction [1]. As it is known, the concept of innovative method (innovative tech-nologies) is a novelty in the field of technology aimed at achieving new knowledge and solutions [2]. A group of authors [3] studied the effect of the degree of grinding on gold recovery using two-stage leaching. In the first stage the ore was subjected to bio-oxidation (active associations of acidophilic bacteria), while in the second stage gold recovery was carried out. In the article "Evaluation of the granulometric composition of the crushed product obtained by crushing "in layer"" [4] describes the granulometric characteristics and evaluates the correspondence of the obtained parameters of the crushed product obtained as a result of industrial tests of the crusher operating "in a layer", according to the equations of Rosin-Rammler and Godin-Andreev. Purpose of work: studying the possibility of maximum extraction of useful components from ore-bearing rocks of black shale for-mation of Sarydjaz area. The relevance of scientific research is to create new highly effec-tive methods of extracting useful components in maximum quantity from ore-bearing minerals of Saryjaz. The choice of this research direction is determined by the need to solve the following problems: Complexity of studying solid mineral deposits, ensuring high profitability of the modern mineral resource base of the Kyrgyz Re-public, taking into account the environmental problems of the coun-try arising from the processing of mining ores Object of study: minerals of black shale formation of Saryjaz ar-ea. Subject of the study: physical, physicochemical and structural characteristics of mineral samples. To achieve the goal the following tasks were solved: Preparatory works were carried out: sampling of rock ore sam-ples, crushing, screening, separation. Carrying out physical and chemical analyses of initial samples. Determination of suitability of the proposed new method of crushing for ore minerals of black shale formation of Sarydjaz area. Analysis, processing and generalization of the experimental data obtained.
