dewatering in mineral processing

dewatering in mineral processing

Mineral processing - Dewatering Britannica

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 common. To this type belong rotary drum, conveyor, and fluidized-bed dryers.
