After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods.

Then wait until the matte cools down, during which time, particles of copper sulfide, nickel sulfide, and a metallic fraction will be formed. In the end, you can recover the metals by means of crushing, grinding, flotation and magnetic separation. Besides, leaching one or two metals from the matte also can be used to separate the copper and nickel.

Impact crushers are commonly used to crush rocks with a silica contain under 5% such as coal, limestone, and phosphate. The only reason why you would use an impact mill/crusher or a hammer mill on a high-silica rock is because it might be sticky in nature and rich in clay. Such high abrasion/high silica impact/hammer crusher operation see
