Oct 23, 2017· Oct 23, 2017· The StepbyStep Process of Producing Iron from Iron Ore. Some 34 s 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).

At present, iron ore resources are decreasing day by day, which is characterized by more lean ore than rich ore, more associated ore and complex ore composition. Xinhai Mining, as a mineral processing equipment manufacturer with over20 experience, provides responsible processing technology by different type of iron ores.

Openpit 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation.
