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 1600 o F. This high temp causes the coke to burn and melt the iron.

From there, the ore is transported to a separate facility for smelting, which is: The process of melting the ore concentrate in a furnace to separate the metal. Then, the ore is poured into molds to make bars of bullion. Closure/Reclamation. Once the ore has been processed and shipped away for sale, the final step of the mining process begins.

In a shaft furnace, iron ore descends by gravity counter-current to the flow of reducing gas. The magnetizing roasting process of iron ore can be divided into four steps from top to bottom of the furnace, namely, preheating, heating, reduction, cooling and discharge step, as shown in Fig. 13.2 (Yu et al., 2020).

There are two distinct categories of iron ore mining, surface mining such as open cast or strip mining and underground mining. At the surface iron ore processing plants, the iron ore is put through crushers and ball mills to break it into a uniform and more workable size and then washed with the residue going to tailings.

4.3 Plasma processing of manganiferous iron ore. Manganiferous iron ore is the type of lean manganese ore containing a maximum about 10–15% of Mn. These are of less importance in ferromanganese production; however, reduction roasting and magnetic separation improve Mn/Fe ratio.

Iron ore is dug out of the ground from open cast mines or mined deep underground. The ore is crushed into a fine powder, mixed with water, making a slurry. Clay is added to the slurry and the mixture shaped into pellets and baked, forming a hard shell.

High-grade ore (> 60% Fe content) requires only simple crushing and screening. The generated iron ore lumps are suitable for direct use in the blast furnaces and are shipped by rail to the steel mill. Low-grade ore (< 60% Fe content) undergoes multiple processing steps to increase the overall iron content.

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron (III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.
