Limestone and Dolomite and their Use in Iron and Steel Plant
Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. Basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is the reduction of iron ore to produce iron.

Production
The whole process of making any type of lime all begins at the limestone quarry after careful surveys. Most limestone is extracted through blasting. Behind the rock face, holes are drilled to place the explosives. When detonated, the explosion dislodges each time up to 30,000 tonnes of stone. Today's blasting makes use of the latest ...
