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.

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (, ash) from relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
Coal Beneficiation at NETL focuses on both enhancing the value of coal as a feedstock and developing new highvalue products derived from coal. Research includes testing of laboratory and pilot scale technologies to produce upgraded coal feedstocks and additional revenue producing products.
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 gasification is said to have greater efficiency than conventional coalburning because it can effectively use the gases twice: the coal gases are first cleansed of impurities and fired in a turbine to generate electricity. Then, the exhaust heat from the gas turbine can be captured and used to generate steam for a steam turbinegenerator.
Coal Beneficiation Technology Options For the beneficiation of coarse coal (larger than 56 mm), there are basically two wet routes: with dense medium based technologies, or with wateronly technologies. Flotation and agglomeration principles will not work since the particles are too large and
