Phosphorite Ore Mining Solution - Mineral Processing

Phosphate rock is a kind of ore with good grindability. Therefore, the grinding process of phosphate rock usually adopts one-stage closed-circuit grinding process or two-stage one-closed circuit grinding process. The grinding equipment used is usually a ball mill. Conventional ball mills (lattice ball mills or overflow ball mills) consume more energy, consume more steel, and have higher grinding costs.
