separation of sand and calcium carbonate

Groundwater | Dissolved mineral sources and significance

Bicarbonate and carbonate. Generated by the action of carbon dioxide in water on carbonate rocks such as limestone and dolomite, bicarbonate (HCO 3-) and carbonate (CO 3-2) produce an alkaline environment. Bicarbonates of calcium and magnesium decompose in steam boilers and hot-water facilities to form scale and release corrosive carbonic acid gas.
