The quantum of coal fines below 6 mm in run-of-mine (ROM) coal has been increasing due to progressive mechanization of mining methods which has created a substantial incentive, worldwide, to develop suitable fine coal beneficiation techniques. The majority of the efforts have been directed toward reduction in ash/sulfur contents in clean coal. The …

Coal washing Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned. The cleaning process consists of a number of steps that results in a product …

Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: – Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.

An important aspect with regard to coal washing is the partial washing of non-coking coal. Under this, less than 13 mm particles are left unwashed and only over 13 mm coal are washed. The washed product (from +13 mm washing) is then blended with unwashed coal to obtain an overall ash content of 34 per cent in coal.

Froth flotation is one of the beneficiation methods in coal washing that exploits the surface hydrophobicity difference between coal, which is naturally hydrophobic, and its associated ash-forming minerals are commonly hydrophilic in nature. This natural hydrophobicity of coal surface acts as an advantage in reducing the ash content of coal …
