Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...

In the processing of coal washing, after crushing and screening, coal need conduct dehydration which including the dehydration of lump coal and slack coal, coal flotation concentration and coal slime. Then drying the coal by using heat energy, dryer machine is the key equipment in this processing.
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.
At Wirral, as at most other collieries, coal-washing was restricted to small coal (slack) where the value of 'dirt' separation was most financially viable. The coal fed to the trough was '..all that will pass through a screen with 1 inch and 1¼ inches parallel bars; the dust, peas, beans, and nuts all being mixed together.
The environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products.In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that contain ...
The term is also used to classify coal according to heat and sulfur content. See Coal grade. Coal Washing: The treatment of coal to remove waste material such as: Dense (heavy) medium processes use a thick solution, usually a mixture of magnetite and water, to separate coal from impurities, such as sulfur, ash, and mercury, by gravity separation.

The practice of washing coal for coking was used to some degree from the very beginning of industrial development in the Birmingham District. Washing was necessary to efficiently produce the quality of coke needed in blast furnaces. Although the lump coal could be coked as it came from the mines, the slack coal, 3/4** mesh, was of little value.
Coal washing was first practised in Europe, and as early as 1826 slack coal was step-washed in the valley of the Tharandt near Dresden, Saxony. The step washer was an early form of the trough washer and owed its name to the presence of two inclined planes, or "steps," in the bottom of its trough.
