Why Mineral Processing is Very Important for the Mining Industry

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.
