What is Copper Concentrate? - Arij Trading

Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is the froth flotation of finely ground ore. Froth flotation involves attaching fine Cu-sulfide mineral elements to bubbles and floating them out of a water–ore

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the

Concentration of the copper(II) sulfate solution by solvent extraction.

Concentration of Ores: Hydraulic Washing, Froth Flotation ...

So nearly all rocks on the planet have some metal or mineral content. However, the concentration of this metal is too less for it to be valuable. Ores usually have a very high content of the desired mineral, but it still must be separated from other mixed impurities, This method is known as the concentration of ores.

metallurgy: Concentration of the Ore Infoplease

When an ore has a low percentage of the desired metal, a method of physical concentration must be used before the extraction process begins. In one such method, the ore is crushed and placed in a machine where, by shaking, the heavier particles containing the metal are separated from the lighter rock particles by gravity.

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
