Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. Mineral processing is conducted at the site of the mine and is a highly mechanical process, with oversight from a central control room.
Flocculation is a characteristic property of colloidal dispersions. The typical classical sol contained sub-microscopic dispersed particles which would pass freely through ordinary filter-paper, and were too small to be resolved by any transmission optical microscope. Consequently, an arbitrary size limit of 0.1 μm could be defined as the upper size boundary of the colloidal range.

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
Much like dewatering, leaching is frequently necessary within mineral processing plants, so if dewatering is a type of mineral processing, leaching falls in line for similar reasons. Learn More About Mineral Processing. Whether there are three, four, or five types of mineral processing depends on whether it's approached from a theoretical or ...
In the mineral processing process, it is often necessary to understand the particle size composition of the material. In order to accurately identify the particle size composition of minerals, sieving analysis must be carried out to know how much each coarse and fine particle occupies in the mineral material.
