2018 6 20ensp;0183;ensp;How do we extract iron from its mineral ores? How do we convert it into steel? The raw materials needed i.e. limestone, coke, air and iron ore and the chemistry of the blast furnace are fully described. Why convert iron into steel? How do you make steel? The manufacture of steel alloys is further described. Scroll down for revision notes on extraction
The case for AL versus HPAL has been debated for many years and gives rise to a substantial list of relative strengths and weaknesses as summarised in Table 1. Reid and Barnett (2002) concluded that for AL to be competitive with HPAL, it would have to give good recoveries, allow acceptable acid consumption and produce low residual iron in

2018 9 11ensp;0183;ensp;Iron processing Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive
2015 7 17ensp;0183;ensp;This page starts by looking at the extraction of aluminium from its ore, bauxite, including some economic and environmental issues. It finishes by looking at some uses of aluminium.
Iron normally does not occur as a free element in the earth. In fact, iron was not of much value to humans until they learned how to free iron from its compounds.
Aluminum is manufactured in two phases the Bayer process of refining the bauxite ore to obtain aluminum oxide, and the Hall Heroult process of smelting the aluminum oxide to release pure aluminum.
