Plasma Processing of Iron Ore | IntechOpen

Minerals in the ore are detected as metal oxides, hydroxides, carbonates, and also associated with gangue as silicates, aluminates. The silicates and aluminates phases are not only difficult to reduce but also consume high flux and energy for which ores with high content of such phases are commonly discarded at the mines site itself.

The Step-by-Step Process of Producing Iron from Iron Ore

Category: Indian Mining, Iron Ore, Iron Ore Production 3 Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).
