And advances in the basic theorectical research and production technologies by utilization of local nitrate mine to produce salt nitrate are introduced in this paper.

Some research results and progress in the world and author themselves' achievements on flotation principles of silicate minerals are summarized.

The adsorption behavior of metal ions on the silicate minerals such as quartz, beryl, spodumene, lepidolite, garnet, and the flotability of such minerals activated by the metal ions were studied.

Effect of Metal Ions on Dispersity of Fine Aluminum Silicate Minerals;

Based on the frame and capability of silicate,the paper introduced the theory and actuality in research about silicate disposal heavy metal pollution in soil,expatiated the method of dealing with the heavy metal pollution through the change of character of silicate from environmental mineralogy.

FTIR Study of Mechanicochemical Activation on Silicate Minerals;

The silicate minerals, including montmorillonite, sepiolite and palygorskite in this paper, are compared with traditional desiccants in components, structures and capability of moisture adsorption.

An iterative least square method was used for the evaluation of standard Gibbs free energy for the formation of silicate minerals in order to remove some of the limitations of the earlier exponential regression method.
