Why Opposition to New Cement Plants Using Coal .Traduire cette page

Half or more of the mercury going into a cement kiln can be from the coal. Yet the fact is that those few cement plants that have major issues with mercury emissions have these concerns because of mercury in their raw materials, not in the coal they use. The simple fact is that the relatively small amount of mercury found in coal is easily dealt with in the cement manufacturing process and ...
