Basic properties of environmental mineral materials including surface adsorption, porous filtration, ion exchange and heat effect as well as chemical solubility are put forward in this paper. They can be widely applied to such fields of tacking contamination and renovating environment as quality improvement of surface water, groundwater, rivers, lakes and ground reservoirs; improvement of soil; disposal of unclear waste; purification of domestic sewage; collection of smoke and dust and treatment of waste water. The prospective investigation and utilization of environment mineral materials are dealt with in detail with the emphasis placed on the prevention and cure of soil contaminated by heavy metals, quality improvement and treatment of surface water and groundwater and collection of smoke and dust in burning coals. The Fe,Mn and Al oxides and hydroxides together with clay minerals in soil are favorable to adsorbing 299 heavy metals in soil systems. Contaminated surface water and groundwater can be treated by natural minerals, especially those having properties of surface adsorption, ion exchange, porous filtration and chemical solubility. The metal minerals containing elements of changeable va- lences such as Fe, Mn and S can be used as good reductants or oxidants to react with pollutants in waste water. The heat effects of natural minerals and their modified products are helpful to fixing sulfur dioxide and fine grains of carbon during the burning of coals. The effective, economical and simple methods of pollutants disposal by natural minerals embody natural self_purification in inorganic world, analogous to well_known biological purification by natural plants in organic world.
