Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Rock Crushing Process in Mining

Let’s follow a rock through a crushing cycle to see what variables will have to be controlled. First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher “breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can’t fall through will

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

The Mining Process Waihi Gold

Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from underground. See more detail on mining. 2. Crushing
