Mineral processing metallurgy Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations

Milling Mineral Processing Extractives Hub

Mineral Processing. 5. Milling. Crushing typically takes Run-of-Mine (ROM) ore down to particle sizes ranging from 6mm to 25mm, depending on the type of processes to follow. Crushed ore is fed into Mills in which the ore is mixed with water and may be ground down to a particle size, in the case of gold and copper, of about 75 microns (0.075mm

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. Less abrasive and softer rocks or stones
