from . In the 12th century, men started to mine from rock. They learnt how to recognize rock that contained and broke off pieces of rock by lighting fires against it, to make it brittle. The work was done from the surface down, excavating the rock in opencast mines and following the veins of .
This concentrated is mixed with limestone CaCO 3 and Coke and fed into the blast furnace from the top. It is in the blast furnace that of occurs. The of is a long and subdued process, that helps in separating the useful components from the …
At bottom of furnace is chemically reduced. blast reacts with coke carbon dioxide and carbon monoxide are formed at temperatures of up to 2000 °C. carbon monoxide removes oxygen from resulting in pig production. Slag is formed from other components and additions. Casting bay
· cast is usually from oxide haematite. This process involves the following steps: 1 Concentration. is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. crushed is concentrated by gravity separation process in which it is washed with water to remove clay, sand, etc. 2 Calcination

· 26 Fe: 18 Ar, 4S 2, 3d 6 is found in the earth’s crust in the form of natural ores which contains different oxides mixed with impurities such as Silica SiO 2, Al 2 O 3, CaO, and MgO, and some harmful impurities such as s, p and As, The suitability of the in the of economically depends on three factors which are:
from using a Blast Furnace. Introduction. The common ores of are both oxides, and these can be reduced to by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air.
