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.

Crushing Minerals This technology increases the extraction of gold and associated metals up to 98% (possibly even more – everything depends on the initial ores and the gold distribution there). The basis of the proposed technology is Electro Hydro Impact (EHI) ores and technogenic wastage disintegration and Magneto-Pulse (MP) flotation concentrates (gravity concentrates) and flotation tailings activation.

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.

Laboratory Crushing Tests - Mineral Processing & Metallurgy

The first step in minerals beneficiation of an ore is normally crushing which has been defined “as the operations required to reduce run-of-mine ore to grinding feed size”. It would therefore follow that the first metallurgical testing should be conducted on run-of-mine ore but, due to its size, this would be rather impractical.
