Copper Concentrated Gangue

Copper extraction - Wikipedia

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically grade between 37% and 40% copper-in-concentrate…

Gangue | geology | Britannica

In mineral deposit …of valueless minerals, collectively called gangue. The more concentrated an ore mineral, the more valuable the mineral deposit. For every mineral deposit there is a set of conditions, such as the level of concentration and the size of the deposit, that must be reached if …

copper concentrated gangue -

The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper .

Copper and Pyrite Separation by Selective and Sequential ...

The Problem with copper-pyrite ores. The major portion of the gold is associated with the copper but the pyrite contains appreciable gold values also. The demand for pyrite for sulphuric acid also gives added incentive for the recovery of the pyrite in a marketable concentrate. The sulfide minerals in the ore are chalcopyrite and pyrite and the gangue is siliceous.

Concentrating – separation of the copper mineral from the gangue. The copper concentrate formed in this stage contains about 15% of copper.The gangue is absorbed by the slag and removed. Read more


Concentrate “A” has the sulphides being mostly chalcopyrite and some pyrite and a higher gangue fraction. Concentrate “B” distributes its copper mostly between chalcopyrite and tennantite and has considerably more pyrite. The mercury mineralogy for the two concentrates …

Copper Mining and Processing: Processing of Copper Ores ...

The slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.

Copper Ore Processing Methods

Ores in which the copper occurs in the form of fine sulfide mineral particles disseminated throughout the gangue and which are treated by fine grinding and flotation. These ores are represented notably by the so-called porphyry-copper ores.

COPPER Copper production - TU Delft

Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 % Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue.

Copper processing - Roasting, smelting, and converting ...

In the hydrometallurgical processes, the ore or concentrate is brought into close contact with a leach solution (frequently sulfuric acid) that dissolves the copper and leaves a residue of gangue (and frequently precious metals). Various systems, some quite complex, are used to bring copper minerals into contact with the leach solution, wash and filter the residue, and finally purify the solution to remove …

Copper Flotation - Mineral Processing & Metallurgy

Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate.

Copper Mining and Extraction Sulfide Ores

After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate. It is valuable enough to ship to other plants and other countries for processing. For example China, Germany and Japan are major copper producers that use concentrate from around the world.

Copper Concentrate

Copper Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value.
