Abstract: The principal characteristics of mineral materials were analyzed.The technological feasibility, application potentials and the significance of nano technology application in mineral materials were explained.Test results show that the combination of mechanical grinding, dispersing and surface modifying benefits the preparation of mineral nano powders.Mineral fibers can be split to nano diameter scales at the condition of proper selection of dispersing agents and methods according to the surface features and utilization requirements.Nano intercalation or film coating of layered minerals such as vermiculite and mica as well as manufacturing of mineral nano pore materials and nano composites can also be practicable and have vast foreground.The development of mineral nano materials is probably one of the important means to prepare nano materials at low costs and is favorable to the promotion of the nano materials industrialization and to the sustainable development of human society.
