Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals.

Crushing. McLanahan offers a variety of crushing solutions to reduce minerals such as coal, salt, granite, copper and iron. Minerals are liberated from the waste rock and reduced in size through the primary, secondary and tertiary stages of crushing, by equipment that utilizes impact, attrition, compression or shear forces.

crushing. Mineral processing generally involve four operation stages. They are: 1) Comminution — rock size reduction; 2) Screening — separating particle sizes by screening or classification; 3) Concentration — gravity separation, magnetic separation, flotation separation and so on methods. 4) Dewatering — solid/liquid separation.

Industrial rocks are rocks utilized as such, without specific mineral separation processes, as raw materials for making products. As examples, the rocks used in making stone wool or soapstone for fireplace manufacturing can be classified as industrial rocks. They can also be classified as natural stone, whereas talc and magnesite floated from soapstone, are industrial minerals. These

In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed. This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a
