Coal beneficiation: theory and practice
Coal beneficiation. After mining, coal is washed to remove impurities including ash and to increase its heating value. Preparation plants remove rock, sulfur, and other particulates from the run-of-mine coal. These plants also allow mining companies to sort coal based on quality, enhancing their ability to serve customers' various …

Phosphate Beneficiation
Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process. The phosphate ore, or "matrix" as it is called locally, contains three different mineral groups which have to be separated from each other.

22.4: Beneficiation
Page ID. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and ...

Bauxite Beneficiation: An Approach to Value Addition in Mining …
The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values. This often requires more complicated processes, such as the use of a high-intensity wet magnetic separator, with fine grinding of bauxite to liberate the iron minerals.
