以含有不同矿物组成的含钾矿粉为材料，用硅酸盐细菌进行解钾试验。结果表明，每克含钾矿粉最多能释放７７．３μｇ水溶性钾，占矿粉全钾量的平均比率仅０．０５６％；经硅酸盐细菌分解后的含钾矿粉进行Ｘ－射线衍射分析，硅酸盐细菌对含钾矿物的晶体结构几乎没有产生破坏性作用，含钾矿粉所含主要矿物的相对含量变化不大，硅酸盐细菌表现不出明显的解钾效果。
Potassium-containing ore powder with different mineral composition is used as material, and silicate bacteria are used to carry out potassium-releasing test. The results showed that 77.3 μg of water-soluble potassium could be released per gram of potassium-bearing mineral powder, accounting for only 0.056% of the total potassium content of mineral powder. The potassium-containing ore powder decomposed by silicate bacteria was used for X-ray Diffraction analysis showed that silicate bacteria had little destructive effect on the crystal structure of potassium-bearing minerals, and the relative contents of the major minerals contained in the potassium-bearing fines did not change much. Silicate bacteria did not show obvious potassium-releasing effect.
