mineral dressing of metal ore - Induzin
Mineral processing—sometimes called ore dressing, mineral dressing, or milling—follows mining, and it prepares the ore for extraction of the valuable metal in the case of metallic ores and produces a commercial end product from products such as iron ore and coal. It is also a process of physically separating the grains of valuable minerals

Mineral dressing (= Orebeneficiation)
2009-5-16 Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched

Mineral Processing and Ore Dressing
2016-6-2 A preliminary crushing to the necessary fineness is made, in some cases as coarse as 2″, and then the ore is subjected to a separation through a heavy mineral suspension. The concentrated values are then further treated by finer grinding, flotation, or whatever indicated treatment is required to

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 milling costs and low throughput as well as an increased need for chemicals in flotation.

This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.
