Identification of Coal and Gangue by Feed

ABSTRACTWhile coal is the major power source around the globe gangue is unwanted in power plants Thus separating gangue from coal is a crucial part in the preprocessing step of mining With the development of the computational technologies it is possible to find one way to enhance the effect of gangue separation By establishing a coal-gangue separation system based on the difference Get Price

The Types of Coal Composition Usage and Energy Value

Dec 17 2018The international standards organization ASTM (formerly American Society for Testing and Materials) has issued a ranking method for classifying grades of coal formed from biodegraded peat-based humic substances and organic material or vitrinite The coal ranking is based on levels of geological metamorphosis fixed carbon and calorific value Get Price

Mining

Coal mining and fracking are both types of mining but they present additional problems that can be addressed with the methods described below Coal Mining In addition to the sources of pollution listed above coal mining produces coal slurry (also known as coal sludge) in the process of beneficiation The coal is washed with water and chemicals as a way to help it burn more efficiently [22] Get Price

COKING COAL BENEFICIATION

Jul 30 2018In the composite beneficiation system of coking coal in India usually three types of products are obtained – clean coal middlings and rejects It is observed that the proportion of middlings is rising day by day on one hand and on the other the yield of clean coal is decreasing in the washeries because superior grade raw coal is depleting gradually Get Price
