Copper Ore Types: Sulfides vs. Oxides | An Investor's ...

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

Gravity Separation

Dec 11, 2019· The separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressing. It is a necessary, and often significant, aspect of mining. It can be a complicated process, depending on the nature of the minerals involved.

copper concentrated gangue

The gangue particles can consist of a range of silicate minerals from quartz to talc and clays. Carbonate mineral gangue can also be present. When liberated, typical copper sulphide minerals are relatively easy to float. When there are no overriding metallurgical issues, producing a sufficiently high copper concentrate grade is often the focus.

The more gangue is discarded in tailings, the more the separation operation is successful. The earth material is mixtures of extractable minerals and extraneous rocky material described as gangue. It is a mineral or a group of minerals that have no economic value in the ore; they also called sterile, unwanted, or undesirable minerals.
