The release disciplinarians, including cumulative K-release and release rate of potassium from five potassium bearing minerals under various solutions were studied. Results showed that the release rates of K from five K-bearing minerals under different solutions follow the order of biotite > vermiculite > phlogopite ≥ muscovite > feldspar. The diversity between the release rates of K from different minerals under the acid solution was significant, follow by the calcium and sodium solutions, the distill water reversed; it depended on the structure of the minerals. Different ions had different abilities to promote the release of non-exchangeable K from different minerals: H+ >> Ca2+ > Na+ > H2O > NH4+. With the increase of the availability of mineral K, H+ and Ca2+ had greater effect on mineral potassium release. Furthermore, the effects of H+ and Ca2+ on biotite, phlogopite, and feldspar were distinct. To vermiculite and biotite, Ca2+ accelerated the release of potassium distinctly rather than Na+. However there was no difference between Ca2+ and Na+ when they extracted other three types of mineral. However, NH4+ restrained potassium release from every kind of minerals remarkably, comparing to phlogopite and muscovite, the effects of restrain on vermiculite and biotite were stronger.
