2. Commercially viable Limestone (the primary component of clinker) deposits are limited in the coastal markets in the country and the import of clinker will allow conservation of natural resources. Osho Cement has thus aligned itself with the government policy for raw material beneficiation as stated in the New Growth Policy. 3.

Many countries around the world have abundant cement grade limestone deposits. But in cases where access to cement grade limestone is expensive or limited (for example – located in environmentally sensitive areas), a dry beneficiation process such as STET can assist in generating a long-term supply of high-grade limestone from lower grade varieties.

Limestone use for cement. Another important use of limestone is producing cement. Cement is produced by burning finely crushed limestone with secondary raw materials such as shale, sand, and fly ash. The resulting product, called “clinker”, is then mixed with gypsum and finely ground. The most common use of cement is in the production of
