Coal is an abundant fuel source that is relatively inexpensive to produce and convert to useful energy. However, producing and using coal affects the environment. Effects of coal mining. Surface mines (sometimes called strip mines) were the source of about 65% of the coal mined
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: – Drydeshaling: Noncoal or shalycoal is removed without using any liquid media.

Nov 15, 2017· Coal impacts: water pollution. When you burn charcoal in your grill at home, ash is leftover. The same is true for coalfired power plants, which produce more than 100 million tons of coal ash every year. More than half of that waste ends up in ponds, lakes, landfills, and other sites where, over time, it can contaminate waterways and drinking water supplies.

Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining. Flotation offers a very satisfactory lowcost method for recovering a fine, low ash, clean coal product at a profit.
Coal preparation, or beneficiation, is a series of operations that remove mineral matter (, ash) from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

COAL MINING AND THE ENVIRONMENT Philip J Lloyd1 Energy Research Institute, University of Cape Town Abstract The environmental impacts of coal mining in South Africa are reviewed. The primary impacts arise from mining, particularly underground mining, largely because South African coal mines are relatively shallow.
