The result of this work has shown that AGBAJAIron Oreif properlyprocessedcan be used in our metallurgical plants and also can be exported sincesulphurcontents of theorehave been reduced drastically.

How do youremove iron from iron ore- Answers.Iron orecan be found all over the world, in the form of rocks and other minerals. To be economically viable for mining,iron oremust contain at least 20%iron.

Oresnear the surface can be quarried afterremovalof the surface layers. Theoreis treated with dilute sulfuric acid. This trickles slowly through theoredissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of thisprocessare: See for further information on the leachingprocess.

This moltenironmay be utilized as castiron. A high purityiron, such as wroughtiron, requires the completeremovalof carbon from thisiron. Likewise, the steel-makingprocessrequires theremovalof other impurities likesulfurand phosphorus from molteniron. Many other different types of steel also are fabricated from this molteniron.
