copper ore is usually in the form of malachite, needs to be refined through chemical method.
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
Copper ore is called CHALCOPYRITE.
To separate copper from its ore, the process is called smelting. The copper and ore are heated and the copper turns to liquid which is then poured from the smelter.
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.
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.
Concentration of ore Unwanted rocks, sand and grit from the mineral ore are called gangue or matrix. These have to be removed so that the mineral ore is concentrated with higher percentage of metal. Ores are mined from deep within the earth's crust in the form of rocks. The minerals are embedded in these rocks. The rocks are first crushed into smaller pieces by crushers. Then they are ground to powder by ball mill and other processes so that powdered ore is obtained. Depending on the type of ore, hydraulic washing, froth floatation process, magnetic separation and chemical separation techniques are applied for concentrating an ore.
Copper Ore.
copper
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.
