  • Limestone

    Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscsIts major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3)A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2...

  • The Extraction of Iron

    Iron ore is not pure iron oxide - it also contains an assortment of rocky material that would not melt at the temperature of the furnace, and would eventually clog it up The limestone is added to convert this into slag which melts and runs to the bottom The heat of the furnace decomposes the limestone ,...
