Extraction of Metals from Ores – Different Processes …

Obtaining metals from this ore is much easier. For example, Haematite ore ( Iron) and Bauxite ore (Aluminium) Sulphide Ores- In this particular ore, the metals are present in the sulphide form. Since it is difficult to extract metals from this ore, they are usually converted to oxides with the process of metallurgy.

THE EXTRACTION OF METALS

Aluminium, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminium is bauxite - which contains from 50 - 70% of aluminium oxide.

Extracting aluminium from recycled scrap requires only about 5% of the energy needed to extract aluminium from its ore. Collecting scrap metal and transport to the metal ...

Extraction of Aluminium

Aluminium - Cost and Recycling. Aluminium is the third most abundant element in the Earth's crust after oxygen and silicon. It is the most abundant metal but it is more expensive to produce than iron because of the cost of the large amounts of electricity which are needed for electrolysis - see moles. About half of the aluminium used in the UK ...

Extraction Process of Aluminium from Bauxite Ore

Other major steps in the process are the precipitation of aluminum hydroxide from the sodium aluminate liquor and the calcination of the aluminum hydroxide to produce aluminum oxide (alumina). In this study the minus 1.5″ bauxite ore is ground to minus 3/16″ in a Steel Head Rod Mill operating in open circuit.
