Limestone & Pyroxenite
Limestone is calcareous sedimentary rock composed of mineral calcite (CaCO3) which upon calcination yields lime (CaO) for commercial use. Cement and Iron & Steel are the major consumers of limestone. It is also consumed in chemical industries like calcium carbide, bleaching powder, soda-ash, precipitated calcium carbonate, etc.
Pyroxenite is also an ultrabasic rock consisting of pyroxenes typically contains 36 to 42% MgO and 36 to 39% SiO2; There is a rising trend in use Pyroxenite in sintering and as a fluxing agent in blast furnace in place of dolomite. Pyroxenite is Magnesium Silicate mineral, which is used as flux in Steel making.
Currently Limestone is being sourced locally in the UAE and being supplied to various Steel and Cement plants in India.
