2018-5-2 · 2018-5-2 · Current copper ore dressing process includes following stages: firstly, crush the raw ore to a certain size with crushing and grinding equipment, then useful minerals realize full monomer dissociation; Secondly, use certain copper ore dressing process and copper processing equipment to isolate useful minerals according to ore properties.

Ore-dressing meaning. Any treatment of an ore used to concentrate its valuable constituents (minerals) into products (concentrate) of smaller bulk, and simultaneously to collect the worthless material (gangue) into discardable waste (tailings).

Ore dressing definition is - mechanical preparation (as by crushing) and concentration (as by flotation) of ore.

ore dressing. [ ′ȯr ‚dres·iŋ] (mining engineering) The cleaning of ore by the removal of certain valueless portions, as by jigging, cobbing, or vanning. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc.

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. Real-time monitoring of grain size and concentration in ore slurries. The extraction of raw minerals begins with the mining of rich ores, which are then cut up in crushers and grinders. The pieces of rock initially weighing tonnes are ground down to a few tenths of a millimetre. This grinding process, which often covers six ...
