Iron and Steel Quicklime both high calcium and dolomitic enjoys its most extensive use as a flux in purifying steel in the electric arc furnace (EAF) and basic oxygen furnace (BOF). Lime is particularly effective in removing phosphorus, sulfur, and silica, and, to a lesser extent, manganese.
Another advantage of using highgrade iron ore is that it reduces coking coal consumption during hot metal production. This means steelmakers can use highgrade iron ore as a way of reducing coking coal costs, which becomes particularly important in a high coking coal price environment.

Neveu and Arnou produced pig steel with to per cent, sulphur from ore containing to per cent, sulphur. The Domnarfvet runs show that from a charge containing per cent, sulphur a pig iron and occasionally a highcarbon pig steel was made containing less than per cent, sulphur.
It is the product resulting from the smelting in the blast furnace of iron ore, coking coal and limestone. Pig iron is made by smelting iron ore into a transportable ingot of impure high carboncontent iron in a blast furnace as an ingredient for further processing steps.
