Приоритетные направления повышения селективности раскрытия минералов в процессах подготовки руды к обогащению

Abstract

The physical basis for the rational organization of the processes of preparing ores for enrichment is selectivity disintegration. Increase the selectivity of the destruction of ores without increasing sludging possible guidance in ore lumps. Chopping network initiating cracks on the planes connection minerals. This is achieved by rational management of mining operations (an increase in consumption of explosives, reduced well spacing, variable speed explosion, etc.), as well as preliminary softening ore before being fed into the mill, for example, with the use of electropulse impacts or in a layer of crushed ore lumps. The examples of the initial concentration and weakening of ore. Improves the quality of the concentrate by 30% relative, and the extraction of 8% absolute. Softening ore brings significant benefit to national economy.
