Research on the Relationship between Multi-Component Complex Ore and Its Component Minerals’ Grinding Characteristics under Abrasion Force

The relationship between the grinding characteristics of polymetallic complex ore and its component minerals, pyrrhotite, sphalerite, quartz, under action abrasion was studied, based on batch experiments theoretical analysis methods selective grinding. results show that when subjected to abrasion, crushing effect enhanced by existence is, sphalerite plays a positive role in ore. reduced pyrrhotite quartz negative In addition, had more prominent speed minerals decreased exponentially with time, instantaneous 0 min negatively correlated feed sizes. rapidly decreasing trend reached threshold time 4 min. can provide some guidance for study multi-component ores subsequent process.
