The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.

Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two ...

How Do We Decarbonize Iron and Steel Manufacturing? Traditional steel furnaces burn fossil fuels to reach the temperatures needed to smelt raw iron and carbon into steel. Process emissions are created when carbon is used to remove oxygen from iron ore, reducing it to pig iron, the key feedstock in the steel industry.

The first step in this process is crushing and grinding the ore to a fine powder. This powdered ore is then subjected to a process called magnetic separation, where magnets are used to separate the iron particles from other minerals present in the ore. This helps in purifying the iron ore and increasing its iron content.
