Copper ore is mined either at via open pit mines or underground mines. The beginning for all copper is to mine sulfide and oxide ores through digging or blasting and then crushing. In the crushing process, the copper ore is broken into small grain sizes of less than 25 centimeters in diameter by primary crusher.

The conical shaft core rotates and moves by the driving of the eccentric sleeve, causing the surface of the broken wall to be close or leave the surface of the rolling wall, therefore, the material is continuously crushed by the crushing and bending in the annular crushing cavity composed of the fixed cone and the moving cone.
The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6. Wet, sticky and extremely hard or tough feeds will tend to reduce crusher capacities.
The materials that larger than the particles are returned to the sand making machine and continue to be crushed. Small substances are sent to the sand washing machine for cleaning. The cleaned materials are sent to the finished product pile by the conveyor.
