The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).

Polymetallic weak magnetic iron ore refers to the phosphorous hematite, siderite. Most mineral processing plants adopt gravity separation – froth flotation – strong magnetic separation process or a combining process to the extraction of iron ore, and then use the flotation process to recover phosphorus or sulfide.

Mining iron ore or other iron-bearing materials from the ground is the first step to make iron and steel. Iron ores are rocks from which metallic iron can be economically extracted. These rocks are usually found in the form of hematite (Fe2 O 3) or magnetite (Fe 3 O 4 ).

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag.

Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation.

Extraction of Iron. The cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps: 1) Concentration. The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. The crushed ore is concentrated by gravity separation process in which it is washed with water to remove

GENERAL OVERVIEW. Iron is extracted through a method called reduction. Raw materials used in the extraction of iron are: Oxygen has to be removed from iron (III) oxide chemically to obtain iron. Iron (III) oxide is reduced when oxygen is removed from it. A blast furnace is used for this process [Figure 4].
