Mineral processing removes impurities from the ore and allows to produce of a clean product of higher quality. For example, silica sand for metallurgy applications that contains iron impurities less than 0.1% has a higher price than which includes more than 0.1%. But, an amount of 0.3% iron or higher isn't acceptable.

In this paper, the beneficiation of rejected phosphate washing sludges (Ps) was investigated using acid leaching methods. Chemical analysis showed that these sludges are a low-grade ore (15.84% P2O5). The optimum milling parameters have helped to increase the P2O5 grade to 18.51%. Then, the effects of three different organic acids (acetic, lactic, and …

The safe alternative in mining - Mineral Processing. Wet, fine-grained tailings from mineral processing can be avoided completely if the entire ore beneficiation is effected in a dry process [4]. Whether dry processes can be employed often depends on the degree of ore purity. For iron ore, dry processing is possible for an iron content > 60 %.
