coal beneficiation wet process
Coal Beneficiation - an overview | ScienceDirect Topics
Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

Fluidized Bed Dry Dense Medium Coal Beneficiation
2021-9-10 · Abstract— Coal beneficiation in South Africa is currently conducted mostly on a wet “float and sink” basis. This process is heavily water intensive and also potentially polluting. Dry beneficiation alternatives are being sought. The alternative of dry dense medium beneficiation using a fluidized bed was investigated.
