copper extraction and purification chemguide

The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2.

From Ore to Finished Product Copper

Copper ore is extracted using two basic methods of mining open pit or underground mining. 3. Processing of Copper Ore. The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps. 4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is

Innovations: Introduction to Copper: Mining & Extraction

The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate. Today, more than 13% of all "new" copper is produced from leachates, which are normally concentrated using solvent extraction (SX) and stripped of their copper content by

The copper ores being mined in 2010 are too lean in copper (0.5–2% Cu) to be smelted directly. Heating and melting their huge quantity of waste rock would require prohibitive amounts of hydrocarbon fuel. Fortunately, the Cu–Fe–S and Cu–S minerals in an ore can be isolated by physical means into high-Cu concentrate, which can then be smelted economically. The most effective method of

Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

The methods of extracting copper as well as other metals found in these nodules include sulphuric leaching, smelting and an application of the Cuprion process. For minerals found in land ores, they are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.
