Extraction of iron from Haematite. 1. Crushing and pulverization. Big lumps of ores are crushed using jaw crushers to get crushed ore which is pulverized using a pulverizer or stamp mill to get powdered ore. 2. Concentration by gravity separation. The powdered ore is washed with an upward stream of water.

The basic extraction of metals from ores has the following steps. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation.

Ilmenite is a black iron-titanium oxide (FeTiO 3) with the main mineral components of hematite, magnetite, pyrite, pyroxene, and amphibole. Ilmenite in placer deposits often contains a large amount of slime. Ilmenite mineral's Mohs scale hardness is 5-6. It is weakly magnetic and has a granular, plate, flake, and scale structure.
Details
Haematite ore consists of iron which is separated from the impurities by using magnetic separation method in which magnet attracts the ore particles towards it and the unwanted non magnetic impurities are left behind.

Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails, wire, car bodies, ship building, girders and bridges amongst others.

Gravity separation is relatively easy when the quotient is greater than 2.5. As the value of the quotient decreases, the efficiency of separation decreases. Below about 1.25, gravity separation is not practically feasible. The specific gravity of hematite is 5.5 to 6.5 whereas it is 4.1 to 4.3 for goethite. Specific gravity of quartz is 2.6.
