Extraction of Iron Concentration of Ore - An Overview

2019-09-23  Concentration of Ore The extraction of iron begins with concentration through calcination which is a process in a limited supply of oxygen applied to ores to bring thermal decomposition. An ore of a metal is an impure source. It consists of many impurities other than metal such as sand, clay, etc.

Efficient enrichment of iron concentrate from iron ...

2020-03-13  According to the thermodynamic analysis of iron ore reduction process mentioned above, this was due to the excessive concentration of carbon monoxide, which would reduce a part of newly formed magnetite to ferrous or metallic iron, thus gradually reducing the iron recovery. However, due to the loss of more weak magnetic iron ore in magnetic separation, the iron concentrate grade was raised.
