Generally speaking, the purpose of ore concentration is to increase the value of an ore by recovering most of its valuable contents in one or more concentrated products. The simplest case may be represented by a low grade copper ore which in its natural state could not be .
Handling guide for copper concentrate in bulk Although copper occurs naturally in a pure state, it''s primarily mined from the minerals chalcopyrite, bornite, and malachite. Copper ore is extracted form the earth, then converted into copper concentrate, which is then roasted, smelted and converted into refined copper.

Concentration of ores: Removal of impurities, such as soil, sand, stone, silicates, etc. from mined ore is known as Concentration of Ores. Ores which are mined often contain many impurities. These impurities are called gangue. First of all, concentration is done to remove impurities from ores.
concentrate via hydraulic entrainment; the wash water replaces feed water that would have otherwise reported to the . concentrate, carrying gangue particles with it. The effect of the water addition is to create a froth where the gas bubbles do not coalesce to the same degree as in nonwater washed froths (Yianatos, Finch and Laplante, 1986 and ...
The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores. The choice of method depends on the nature of the ore. Some important methods are : (i) Gravity separation (Hydraulic washing) : In .
In the next step, called concentrating, the powder is mixed with water and chemicals, which cause copper sulfide ores to float to the top, where they may be separated from some of the other minerals.

There are numerous methods of concentration and the methods are chosen based on the properties of the ore. Hydraulic Washing: This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic ...
