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.

Dewatering is the stage of mineral processing that involves removing the water from the pulp or concentrate, to reduce the moisture content and improve the handling and transport of the product.
Mineral processing involves four general types of operations: comminution or particle size reduction, sizing or separation of particle sizes by screening or classification, concentration by taking advantage of physical and surface chemical properties, and dewatering or solid/liquid separation.
1. Introduction. The tailings generated from mineral processing can represent >95% of the total ore [1].As ore grades decline, higher tonnages are processed, making tailings management more difficult [2].This is reflected in higher costs, increased difficulties in returning water for further processing, and challenges in mine closure and …
