Iron Ore Smelting Process

Mar 13, 2010The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of

Iron and Steel Slag Statistics and Information

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and

Coal Ore

Coal ore is a mineral block that drops coal when mined. Deepslate coal ore is a variant of coal ore that generates at lower levels, when replacing tuff or deepslate. Coal ore can generate in the Overworld in the form of blobs. It generates in two batches per chunk. The first batch attempts to generate 30 times per chunk in blobs of 0-37, evenly from levels 136 to 320. The second batch

Coal steel

Air which is heated to about 1200C is blown into the furnace through nozzles in the lower section. The air causes the coke to burn, producing carbon monoxide which reacts with the iron ore, as well as heat to melt the iron. Finally, the tap hole at the bottom of the furnace is opened and molten iron and slag (impurities) are drained off.

HOW A BLAST FURNACE WORKS

The CaS becomes part of the slag. The slag is also formed from any remaining Silica (SiO 2), Alumina (Al 2O 3), Magnesia (MgO) or Calcia (CaO) that entered with the iron ore, pellets, sinter or coke. The liquid slag then trickles through the coke bed to the bottom of the furnace where it floats on top of the liquid iron since it is less dense.
