Mineral processing - Wikipedia
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle…flocculants in dewatering in mineral processing,Solvays AERODRI® dewatering aids are used to reduce cake moisture in the filtration of mineral slurries, such as sulfide flotation concentrates, iron ore concentrates and coal concentrates, and tailings and alumina trihydrate in the Bayer process.

Dewatering Equipment - Metallurgist & Mineral
Concentrate Thickening & Filtration The concentrate (or concentrates) produced in the facility must usually be dewatered prior to shipment. The first step of the dewatering procedure is usually sedimentation. The design engineer must be extremely careful when developing the size of concentrate thickeners from laboratory data. In the laboratory, concentrates settle extremely rapidly.
