In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores History. A set of Cornish stamps. This section needs expansion. You can help by adding to it. (August 2010) Before the advent of heavy machinery the raw ore was broken up using
The purpose is to crush the raw ore into appropriate size which is suitable for grinding. 2, grinding part: to grind crushed part, further process the ore to get smaller size, in order to match up with floatation separation materials. 3, floatation part: the floatation procedure is an important process for upgrading copper ore.
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.
Ore Dressing Process Innovations. Increased mechanisation of the ore dressing process and public concerns over subjecting women and children to the harsh working conditions of the mines meant that the proportion of bal maidens in the workforce continued to fall, and it is generally accepted that by .

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 ore lumps from the mines have the lump size of 10 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.

These charges varied with the type of ore
The ore dressing process of treating poor hematite includes staged ore milling, size separating, gravitational dressing, strong magnetic dressing and inverse floating. By means of staged ore milling, early separation between iron containing mineral and gangue, returning the intergrowth to next ore milling for further separation, separating milled material based on size, gravitational dressing
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.
