extraction and purification of iron from its ore in an integrated plant

Extraction and separation of manganese and iron

2019-1-15  On the contrary, as for the Fe-Mn ores with high iron content, the iron ions concentration of the solution is high even if the iron leaching efficiency is only 20–30%. The leaching of Fe-Mn ores in the presence of oxalic acid and methanol presents better selective leaching effect of manganese and iron, but it’s uneconomic owing to the high price of the organic reductants.

2021-3-10  Iron ore is used to make iron and steel eg haematite and magnetite. Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides – the carbon is known as the reducing agent. Coke is a cheap and readily made reducing agent.
