Ore dressing has been extensively used in coal industry. The primary mission is to get rid of impurity mixing in original coal, such as gangue, coal gangue and pyrite, thereby reducing the ash and sulphur content in the original coal. The common way for coal dressing is: gravity dressing and floatation.

An overwhelming majority of nonmetal mineral resources seem incapable of being utilized without dressing and purifying process due to the symbiotic relationship with other ores. For instance, the kaolin used in advanced ceramics and paper industry, apatite acting as the fertilizer ingredient, raw mineral material used in building material and electric industry. For the utilization of these nonmetal mineral resources, ore dressing naturally has been considered as the crucial process.

Ore dressing is applied to geological departments by judging the deposit with washability experiment to ore. Moreover, ore dressing is an effective way to separate the monomineral required by rock and mineral identification work as well as heavy concentrate work. Ore dressing has been promoted to a great many economic fields over the years.

To sum up, a great many departments in national economy cannot go without this mineral processing technology. From the initial stage of gravity mineral processing represented by ancient gold rush to current stage where new technology and equipment continuously emerges, mineral processing technology has become a separate discipline. In line with the technology promotion and increasing demands of human beings for raw material and energy resources, mineral processing technology level will be greatly enhanced and its application scope will become larger and larger.
