The process of extracting iron from its ore involves a series of steps that begins with crushing the raw ore to extract the iron mineral content. The iron minerals are then separated from the rest of the ore by washing and magnetic separation. The iron minerals are then roasted to produce a highquality iron oxide that can be further processed ...

Various Zones differ significantly, which may limit the applicability of a particular process to only part of the ore reserves. Processing routes must be able to reject the large iron, silica and magnesia contents. High iron content is a problem for acid leaching processes in general. Magnesia and alumina are also acid consumers.

Iron is the most vital metal in human use. It constitutes % of the crust material and holds third position in abundance after silicon and aluminium. It is rarely found in native condition except in meteorites and some eruptive rocks. It enters into large number of rocks forming silicates and is widely available as oxides.

A typical laterite ore may contain approximately % Ni with 4050% Fe existing in the form of goethite [ (FeNi)O⋅ (OH)⋅ n H 2 O]. Laterite ores contain up to 40% of free and combined moisture, which is removed in the reduction process ( Ray et al., 2014 ). Similar to copper extraction, nickel ores are first beneficiated to produce ...

This type of foundry started in 1 060 The primitive smelting of iron was done in extremely hot ovens. The temperature and ventilation in the ovens were controlled. After the iron had melted, the iron would harden and then hammered to get rid of the silt. Afterwards, it was processed and cut into sheets.

The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80100 feet high and about 25 feet in diameter (Figure 2) in which the roasted ore, coke ...

The pig iron was melted in a running out furnace and then run out into a trough. This process oxidised the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal, known as finers metal or refined iron.
