Wetgrinding is generally used in mineral processing operations because of the overall economies of operation. Theadvantages of wetgrinding are: 1. It consumes lower power per ton of product. 2. It has higher capacity per unitmillvolume. 3. It makes possible the useof wetscreening or classification for close product control. 4.

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high millingcosts and low throughput as wellas an increased need for chemicals in flotation.

Acceptableoreparticles are carried away by water bywet mill, or by air by drymill. The discharge opening is equipped with a discharge grate, and theorepulp horizon of discharge opening is low. These two factors prevent ores from being overly grinded, and iron balls from being dismissed.

Mineral processing - Mineral processing - Dewatering: 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.

Sep 01, 2019· Water scarcity dictates to limit the use of waterin oreprocessing plants particularly in arid regions. Sincewetgrinding is the most common method for particle size reduction and mineral liberation, there is a lack of understanding about the effects of dry grinding on downstream separation processes such as flotation.
