Indian Iron Ore Scenario : Low Grade Iron Ore Beneficiation
Indian haematite ores are generally rich in iron content but usually have high Alumina. The current mining methods generate a lot of fines, almost to the tune of 60%. Over the years these fines got accumulated causing significant environmental impact. Also the slimes generated during beneficiation contain an iron value of 4055%, which are being discarded till now and is dumped in mines heads ...
What Is Iron Ore Beneficiation? (with pictures)
Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purifiion. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore. It responds best to what is known as gravity separation as well and several types ...

Experiment No. 4 Date: ESTIMATION OF IRON IN HAEMATITE .
Principle: Haematite is an oxide ore of iron, existing as ferric oxide (Fe 2 O 3). On treating with HCl, ferric oxide dissolves in the acid as ferric chloride. Fe 2 O 3 + 6HCl → 2FeCl 3 + 3H 2 O Since iron in FeCl 3 is already in the highest possible stable oxidation state (Fe3+), it cannot be oxidized further by potassium dichromate solution, which is also an oxidizing agent.. Therefore, it ...
