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

Trends in the Crushing of Mineral Ores Mineral Processing

Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.
