Mineral processing - Dewatering, Filtration, Separation: Concentrates and tailings produced by the methods outlined above must be dewatered in order to convert the pulps to a transportable state. In addition, the water can be recycled into the existing water circuits of the processing plant, greatly reducing the demand for expensive fresh water. Filtration …

In mineral processing, ores must go through a number of different operations to obtain the final products. Thus, mineral processing involves four major steps or stages: (1) comminution or size reduction, (2) size separation, (3) concentration or beneficiation by taking advantage of physical properties, and (4) dewatering.
