5. Processing plants should invariably be coated in mining areas to reduce transport cost. In case of weighty materials like coal it is better to convert it into coking coal or in electricity near the pit heads. 6. There is a great scope for the expansion of several mineral-based industries which open new vista for economic development. 7.

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