Are You Mining Minerals for Cement, or for Concrete? You might think of a cement manufacturing facility as an extension to a mining operation, as cement plants are typically located central to the minerals required to make the cement, which saves the transportation costs and reduces the price of the cement. cement and raw materials suchget price
