AUGMENTING AN INBOUND RAW MATERIAL HANDLING
1. Iron ore, coal, coke and limestone are the major raw materials required for production of steel. The in-bound raw materials are received and unloaded at a Raw Material Unloading Yard (RMUY). The unload-ed raw materials are processed at treatment plants (Coke, Sinter and Pellet Plants) from where they are sent to a blast furnace for iron making.

calcium sulphate (gypsum). A substantial proportion of the raw material is made up of carbonate ore (usually limestone, but also dolomite). This material is generally quarried close to the cement plant. Heating of the limestone in the kiln, to form CaO (calcination), results in the release of approximately 35% CO 2 by weight.

2023.12.8 Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells. Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and
