surface water is a fairly popular method of increasing the pH values and decreasing the concentration of phosphates and heavy metals. According to the Environmental Protection Agency (EPA) recommendations, the increase of water pH should not exceed 1.5. If surface water is the source of water supply, is a process that reduces water contamination.

limestone or fly ash is also important, but due to their higher moisture content, the grinding operation is often carried out in tandem with a drying arrangement. Furthermore, grinding systems must meet several other requirements. As the process accounts for up to 60 per cent of power demand in the cement plant,

calcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impure limestone known as "natural cement rock". Typically, these raw materials are obtained from open-face quarries, but underground mines or dredging operations are also used. Raw materials vary from facility to facility.
