Grinding - Mineral Processing

Determining an optimal grinding size can maximize the recovery of target minerals in the subsequent flotation process. The grinding size is too large, and some ore particles and non-ore particles cannot be separated, thus preventing their flotation. If the particle size is too fine, the bubbles that rise during the flotation will push the very fine ore-containing particles away, preventing them from contacting the

Crushing and Grinding Process - JXSC Machine

The so-called selective grinding is the use of selective dissociation of minerals and selective grinding of the grinding, the purpose is to cause some selectivity in grinding operations. The main purpose of the grinding operation is not to reduce the ore particle size, but to dissociate the useful minerals from the gangue minerals. The ultimate goal of grinding is to obtain the highest monomer dissociation with
