extraction of copper from its ore copper pyrite. Extracting copper from its ores 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 or Get Now extraction of copper from sulphide ore shauryacentre
Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes. The cathode plates are coated with graphite in order to remove depositing copper. The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity.
Jun 17, 2007· It is a "sulfide ore" as the copper is chemically bonded with copper sulfide minerals in clued chalcopyrite, CuFeS2, bornite (Cu2FeS4), and covellite (CuS). The main copper oxide mineral is Cuprite, Cu2O. Copper can also form carbonate minerals such as Malachite, Cu(OH)2•CuCO3 and azurite, Cu(OH)2•2CuCO3.
A. Processing of Oxide Ore. Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (waterbased) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning.

copper extraction and purification chemguide. This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its us Before you get too bogged down in the extraction .
An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. Most metals are extracted from ores found in the Earth's crust. Ores are often metal oxides, although sulfide and carbonate ores are also common.
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 byproduct of this process is used for the extraction of oxide ores.
How are metals extracted from mineral ores? How do we make iron, steel, other alloys, aluminium, sodium, copper, zinc, titanium and chromium. The six linked pages include an introduction to metal extraction or metal manufacture and production. There are detailed notes on the extraction of iron and its conversion to steel. The extraction and manufacture of aluminium and sodium are described.
outline only of the extraction of copper from its ores will be given here, and before this is entered upon, it may assist the reader to state that it may be summed up under the following heads: 1. Roasting processes, intended to expel arsenic and sulphur, and to convert the iron into oxide of iron. 2. Melting processes, intended to remove the oxide of iron by

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.
