In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().Examples of beneficiation processes include froth flotation and gravity separation.. Other economic uses of the term are in use.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
Jul 30, 2018· Operational problems. A coal preparation plant even though very well designed, cannot give good results unless proper care is taken in running it with a well-planned operation and management schedule.

eventually add to the problems of coal beneficiation. The fine coal circuits in coal washeries are intricate, needing close attention and careful operation. Increase in fines in raw coal feed to washeries also adversely affects the material balance in fine coal circuits of the currently operating plants creating operational problems, e.g ...
To avoid environmental problems with the sulfur, coal companies and power plants take measures to remove it before, during and after burning. In pre-combustion technologies (before burning), the coal may be cleaned at the mine, at the power plant or both. When the coal is cleaned at the mine preparation plants, it is crushed and washed.
Utilising the high carbon ash either at a power plant or a cement kiln maximizes the energy recovery from delivered coal, reducing the need to mine and transport additional coal. Some fly ash is contaminated with ammonia due to the injection of ammonia into the power plant's flue gas handling system.
