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 ...

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.

The crude ore from the mines contain a number of solid phases in the form of an aggregate. The valuable portion of the ore is known as mineral while the worthless portion is known as gangue. During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them.

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Nov 16, 2020 The annual output of heavy placer gold in the gold ore dressing plant accounts for about 25% of the annual gold output. When the coarse-grained gold enters the leaching system, the process flow cannot be satisfied due to the long leaching time required, which further affects the tailings and tailing liquid indicators.
