In the next step, called concentrating, the powder is mixed with water and chemicals, which cause copper sulfide ores to float to the top, where they may be separated from some of the other minerals.
copper ore is usually in the form of malachite, needs to be refined through chemical method.
Copper is concentrated through a process called flotation, where crushed ore is mixed with water and chemicals to create a slurry. Air bubbles are then introduced, which attach to the copper minerals and float them to the surface for collection. The concentrated copper can then be further processed to extract the metal.
Copper ore, usually in the form of malachite, needs to be refined through a chemical reaction, rather than a mechanical separation as with washing. It needs to be ground and heated to separate out the copper metal from the compound.
a copper ore
The mineral malachite is an ore of copper.
A refinery separates copper from its ore.
Most copper ore occurs as copper in combination with oxygen, yes.
The most common ore of copper is Copper pyrite CuFeS2 but other ores are also exist.
1. Copper ore is mined and crushed. 2. It must be processed to remove the useful mineral or element. 3. Smelting is the process used to obtain copper. In the smelting the ore is melted and material are removed. After smelting, the copper is refined ,or purified. 4. Then it is made into many types of products used in homes, businesses, and industry.
Copper is typically extracted from the ore chalcopyrite, which is a copper iron sulfide mineral. Other ores that contain copper include bornite, chalcocite, and covellite.
It depends upon nature of ore the most common ore of copper is Copper pyrite CuFeS2. the extraction of copper from this ore involves the following steps, 1-crushing, 2-grinding, 3-concentration of ore, 4-roastiong, 5-smelting, 6- preparation of blister copper and 7- electrorefining of blister copper.
