A mode of the directionally growth of PAn on the surface of NaFe〓P〓rod-like particle was suggested. Some of aniline molecules in the reactants are fixed on the surface of skutterudite particles before the beginning of the polymerization. Other aniline molecules link with the aniline molecules fixed on the surface of skutterudite and form liner chains when the initiater is added into the reactants.

For further understanding the effect of the strain on K-bearing silicate mineral, an experiment with KO2 strain cultured in nitrogen-containing and nitrogen-free medium was conducted. By putting mineral powders into the medium and measuring the concentration of capsular polysaccharides, we concluded that the strain can accelerate the weathering rate of silicate minerals. The results showed that the polysaccharides secreted by the strain in the growth process could help the bacterial to adhere to the mineral surface effectively, and created the bacterium-mineral complex, which formed a mircro-enviorment avail the release of potassium. Another result was that there was higher level of Carbonic Anhydrase activity, which revealed that some exo-protein or enzyme produced by the bacterial had postive impact on the process of releasing potassium ion. We carried out the bacterial fermentation for larger scale production of the bacterial secretion, which was used to sperate, and identify the small molecules related to the mineral-bacterial interaction. After the analysis, it was found that the strain can produce many kinds of small molecules, such as 2-Hydroxybenzoic acid, 4-Hydroxyphenylacetic acid, methyl-4-hydroxybenzoate, etc.

Infrared spectroscopic analysis shows that the water glass is chemically adsorbed on the surface of titanaugite but this reaction is weaker between the water glass and ilmenite; hetero-coagulation will occur easily under weak acidic condition because of the opposite surface charge of ilmenite and titanaugite.

红外光谱分析表明：水玻璃与钛辉石发生化学吸附，而在钛铁矿表面吸附较弱；在弱酸性条件下，由于钛铁矿与钛辉石表面带异相电荷而容易发生异相凝聚，添加水玻璃使二者表面电位均显负电性，矿粒间静电斥力迅速增大，从而减弱矿粒间的异相凝聚。
