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.
By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind. For this, either table or Hydraulic classifier is used. Generally oxide and carbonate ores are concentrated by this method. haematite and cerussite. There are two gravity concentration methods.
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 ...
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.
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 .

Furthermore, all control of the washing operation is centered at a single point. Cyanidation and concentration of gold and silver ores. Factors affecting Thickening rates. As discussed in Chap. II, a number of chemical and physical factors affect the settling rate of ore particles suspended in water or cyanide solution.
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.
Apr 30, 2013· Hydraulic Washing: This is based on the differences in gravities of the ore and thegangueparticles. It is therefore a type of gravity is concentrated by this method.

A. Concentration or Benefaction of the Ore. This is a very important in metallurgy. The ore is obtained from the earth and usually contain dust, stone, quartz, feldspar and other foreign impurities are known as gangue or matrix. The process of separation of gangue from ore is known as concentration.
Isolation of metals from concentrated ore involves two major steps: (a) Conversion to oxide (b) Reduction of the oxide to metal (a) Conversion to Oxide • The concentrated ore must be converted into a form which is suitable for reduction. • Usually the Sulphide ore is converted to oxide before reduction as Oxides are easier to reduce.

First, the ore needs to be concentrated with some processes like hydraulic washing, magnetic separation, etc. then finally the isolation of pure metal is done. Concentration of Ores This is the process of isolation of ore from the gangue. This involves various processes that depend on the properties of the metal ore and the gangue.
