Extraction and separation of manganese and iron from ...

2019-1-15  In the oxide type manganese ore, the manganese is often present in the insoluble form of Mn 4+ and iron often exists in the state of Fe 3+. In order to obtain soluble Mn 2+ , Mn 4+ must be converted into Mn 2+ , therefore, reductants are applied to reduce Mn 4+ into Mn 2+ during the acid leaching process (Named as direct reduction leaching).

IntroductionPyrometallurgyHydrometallurgyElectrolytic ReductionSummarised Notes About Extraction of MetalsThere are only a few metals that occur in their native state on earth. These elements have very low reactivity. I.e, they are not able to form compounds easily. For example- carbon, sulfur, nitrogen, noble gases, gold, silver, platinum, etc. On the other hand, there are certain elements that are reactive in nature and are easily attacked by oxygen, moisture, carbon dioxide or non-metals. These elements occur on the earth’s crust in the form of compounds. In the combined state, Metals are usually found in oxidized for

Purification of Metals, Chemistry tutorial
