What is the role of crushing in the beneficiation process?
Crushing the ore, ore or ore chunks is to be treated, broken by the action of an external force, overcoming the force between the inner part of the sub, the ore particle size tapering process. In the beneficiation process, ore crusher is usually divided into crushing (coarse stage) and (fine stage) two stage grinding. In the concentrator, the crushing of the ore is an indispensable material preparation stage before the sorting operation. First of all, the overwhelming majority of the ore processing concentrator useful minerals and gangue minerals closely together with students, and often into fine particles and even fine-grained disseminated. Only by pulverizing them and dissolving them fully can they be enriched by existing physical beneficiation methods. Secondly, a cutting physical beneficiation methods are limited particle size, particle size is too coarse (useful minerals and gangue unrealized dissociated) or particle size is too small (i.e., excessively pulverized as fine particles> can not be effectively sorted. Beneficiation plants in all sectors, ore crushing process is the highest cost, constitute an important part of the concentrator investment and production costs. Therefore, the basic task ore crushing operations is to provide materials suitable candidate for the job sorting, crushing process work is good or bad, Directly affect the technical and economic indicators of mineral processing.
