Abstract

Abstract

Based on the microwave selective heating potential, the microwave absorption effect of the cassite polymetallic sulfide ore and the effect of microwave-assisted heating pretreatment on grinding were studied. The changes in indicators such as particle size distribution and metal distribution of the ore products before and after the microwave heating pretreatment were investigated to explore new ways of microwave heating-assisted grinding of cassiterite polymetallic sulphide ore. The results showed that there are significant differences in the absorbing ability of the main ore minerals of the cassiterite polymetallic sulphide ore. Among them, jamesonite has the strongest absorbing ability, followed by pyrite and cassiterite. The absorbing ability of sphalerite and gangue minerals are the worst. After the material is heated, the grinding effect of rapid cooling with water is better than that of natural cooling.
