Iron ore consists of various oxides of iron (occurring as iron-containing minerals) mixed with oxides of other metals (such as Al and Si). In the traditional route to produce steel, the ore is first ground and most of the non-iron oxide minerals are removed through various means, a process referred to as beneficiation.The beneficiated ore is then made into various forms of …
