Dewatering improves biomass's capacity to burn efficiently and maintain stability during storage, allowing for further processing and use. Beyond the dewatering step, drying is a vital process that includes removing water from biomass. The moisture content is greatly decreased, increasing energy density, and lowering transportation costs.

Coal slurry is an essential component of mining operations, accounting for more than half of operating costs. Dewatering technology is simultaneously confronted with obstacles and possibilities, and it may yet be improved as the crucial step for reducing the ultimate processing cost.
Dewatering. With few exceptions, most mineral-separation processes involve the use of substantial quantities of water and the final concentrate has to be separated from a pulp in which the water–solids ratio may be high. Dewatering, or solid–liquid separation, produces a relatively dry concentrate for shipment.
The review validated the technical feasibility of the physical beneficiation of REE minerals from coal without a significant particle size reduction to produce high-grade REE feedstocks for leaching.
The removal of water from solid materials by thermal drying plays a significant role in modern mineral processing. A great number of dryer types are available. Convection dryers, employing a flow of hot combustion gases to remove moisture from a pulp stream, are the most …
