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 ...

Scrubbing. Naturally occurring deposits of aggregates and minerals hardly ever meet the gradations necessary for use in our daily lives. When aggregates and minerals are initially liberated from the earth, and even after they are crushed in the processing plant, they can contain lumps or coatings of clay, soft rock, vegetation, crusher dust and other deleterious materials that are not ...

Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.. A method of separating solid particles according to size alone is called screening.
