extraction of copper from ore

copper extraction and purification chemguide

Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction

Copper Mining and Extraction Sulfide Ores

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper

Copper mining and the copper extraction process

If you are thinking of investing in copper, this article explains copper mining and the copper extraction process: how copper is extracted from the earth’s ores. It also summarises where the main copper mining regions are located and identifies who the major producers are. Copper mining. While copper does occur as a native metal, most of the copper used today is mined as ores. The ores occur

Extraction Of Copper Mining, Concentration, Smelting

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore: The ore

Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

EXTRACTION OF COPPER

EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper. Crashing and Grinding The ore

GCSE CHEMISTRY Extraction of Copper Thermal

Extraction of Metals. Extraction of Copper. Copper is sometimes found as native metal. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable. Bioleaching and

Copper Mining and Production Processes Explained

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. The most abundant
