enrichment process of copper ore

Ore enrichment KGHM Corporate Website

A mechanical process of copper ore enrichment is essential for effective smelting. The concentration level obtained at the enrichment stage makes the copper material fit for further processing at the smelter. This processing is required due to the fact that the copper ore deposits mined by KGHM in Poland contain, on average, only 1.52% of copper.

Copper Concentrate Enrichment Process

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps. Some ores have associated problems such as chalcocite-coated pyrite and are difficult

Ore deposits formed by oxidation and supergene enrichment

3) Supergene enrichment may add much where there was little. 4) Leaner parts of the vein may be made rich. 5) Unworkable protore may be enriched to the ore grade. E.g. many of the copper districts would not have come into existence except for the process of enrichment.

Aug 26, 2014· Copper ore enrichment involves mechanical processing which enables an effective management of the extracted ore. As a result, the concentrate contains the amount of copper that can be processed further in a smelter. This process is necessary due to an average 1.52% content of copper in the exploited Polish deposits. The technology applied by

How are copper ores enriched in copper? Yahoo Answers

Apr 19, 2012· 1The enrichment process is produced by metamorphic changes. The responsible agent is pressure. Increases in pressure remove most of the non malleable minerals leaving copper behind. 2 Actually, it is enrichment by attrition. The "enriched" copper minerals are already below the surface. Groundwater is responsible for removing the copper poor minerals, thus producing an enriched zone.

Enrichment of ore Fun Science

The process of removal of gangue particles from ore to increase the percentage of metal in ore is called enrichment of ore. The processes used for removing the impurities from ores depend on the difference between physical or chemical properties of the ore and of the impurities. Methods of enrichment of ore:

SECONDARY ENRICHMENT

SECONDARY ENRICHMENT SECONDARY ENRICHMENT IN CHALCOPYRITE (COPPER) DEPOSITS Secondary enrichment: is an ore concentrating process that occurs when metals are leached from surface rocks and precipitated just below the water table. Leaching: is where elements are dissolved from rocks and carried downwards in solution. A Gossan: is an impermeable cap of iron

Supergene (geology) Wikipedia

In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering.The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.

copper transportation from a source region, but the protore does not need to have high copper content if leaching and precipitation are efficient. Conversely, the second type requires substantial protolith copper content if the copper oxide zone developed is to be of potential ore grade, and requires also that removal of copper be minimal.

Copper Mining and Production Processes Explained

The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting. This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine.

process of copper ore

The main copper ores are: chalcopyrite bornite malachite. Grinding: The ore is crushed then ground into powder. Concentrating: The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting: This is where the chemical reactions start.

Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
