Its main mineralogical composition is CaO·AL₂O₃、CO₂·AL₂O₃ which have stronger activity. Water treatment material production through acid soluble singlestage process can reduce labor power and electric power, and greatly cut the cost, furthermore, its manufacturing equipments is compact and simple, and easily grasped. It is idea raw material for manufacturing aluminium chloride and polyalminium chloride with stripping ratio of over 80%.

 

Mainly used for the material of manufacturing aluminum sulfate, poly aluminium, crystal aluminium, and the substitute of aluminium hydroxide powder. Showing features of low price and high aluminium content.
