METHOD OF DEVELOPMENT OF MINERAL DEPOSITS Russian patent published in 2019 - IPC E21C41/22 E21F15/00 

FIELD: mining industry.

SUBSTANCE: invention relates to the mining industry and can be used in the underground mining of ore deposits. Simultaneously with the mining of standard-grade mining blocks without harmful impurities, ores carry out mining and sorting, according to the conditionality of the ore mass, of mining blocks of conditioned ore-processing minerals with harmful impurities. Laying out of the developed space is produced by sorted fine fractions of ore mass of conditioned ore dressing materials with harmful impurities of ores combined with tails of sorting according to the content of harmful impurities. Leaching them produce reagents that minimize the interaction with harmful impurities. After sorting, a concentrate with a reduced content of harmful impurities is discharged to the surface after blending with ore mass from the mining blocks of conditioned ore without harmful impurities.

EFFECT: technical result of the proposed method is to increase the efficiency of the process by solving a system problem of increasing the through extraction of useful components in the extraction and processing of various sorts of refractory ores with harmful impurities.
