Abstract Beneficiation of lowgrade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, lowgrade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity separators. Hence, alternative beneficiation ...

The origin of mining and mineralprocessing wastes is closely related to the formation of the target resource or minerals. For example, many coal deposits exist in subsided regions resulting from mountain formation; hence, the overlays of coal resources are generally not very thick and consist of relatively inactive sedimentary rocks.

When rockbursts and coal and gas outbursts simultaneously occur in a coal mine, changes in gas adsorption (concentration of ambient methane) and displacement of coal and rock must occur. The coassociated minerals in coal reservoirs can affect the mechanical properties and methane adsorption capacity, which are commonly disregarded. It is important to construct compound molecular structure ...
