Grinding magnetite ore

The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation. The separation step between grinding stages progressively reduces the amount of material to be ground

    Effect of additives on grinding of magnetite ore

    Aug 01, 1991 Investigations have been carried out to evolve a grinding aid useful in grinding a 40% iron-bearing magnetite containing quartz as the major gangue, based on studies conducted with pure magnetite, pure quartz and its synthetic mixture.These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz preferentially over magnetite

    Sep 01, 2021 The ore processed by grinding in the minerals industry is generally composed of two or more minerals, and thus multicomponent formulations are commonly used to simulate the grinding process. In this paper, batch studies were carried out by grinding magnetite, limestone, and magnetite/limestone mixture at different mixing ratios in a laboratory

    Oct 01, 2020 The goal is to perform a comparative interpretation of the application and effects of GAs on dry grinding of magnetite ore (as one the most important ores within Sweden) and the resulting product surface properties. Three different industrial additives employed as GAs, at varying dosages, and compared with a blank condition (without GAs) as the
