Depressors In Mineral Processing

  • Why Mineral Processing is Very Important for the Mining

    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%.
