In order to reduce manufacturing cost of SiAION and promote its utilization,great attention was recently given in world that SiAlON were synthesized from natural non-metallic mineral using carbothermal reduction nitridation.

In this paper, the method, technology, equipment, reagent and mechanism of surface modification of non-metallic mineral fillers are reviewed and the progress of their applications to some important non-metallic mineral fillers such as CaCO3,kaolinite,wollastonite,talc, mica, SiO2 etc, is reported.

It describes fullymethods and technologies for perparation of white catbon black by using non-metallic minerals.

Take example for Fuxin city, the development stratagem and measure of the coal fine processed, the development and utilization of intergrowth mineral and non-metallic minerals, the extension of industry chain, and the broadness of industry group are discussed in this paper.

In this article,we analyse the actuality and development of domestic non-metallic minerals drier,put out the needs on the capability of the new drier for the problems of the equipment at the present time,and dope out the tape of new drier that will be able to appear.

This paper discusses the chemical composition, mineralogical composition and technological property of main nonmetallic minerals including illite ore, kaolinite ore and talc ore etc.

The prospect of development and utilization and quatations of supply and demand on the market of the nonmetallic minerals have been briefly introduced in this paper.

It provides a new way for deep processing and comprehensive utilization of nonmetal ore.

To different pollutant waters, porous and layer-shaped non-metal minerals are adopted, activated and compounded.
