本研究探究了AMCC10037、AMCC10079、AMCC10080和AMCC10096 4株菌在尾矿处理过程中不同培养状态下的细菌密度、p H值及硅、钾元素的释放性能,采用ICP-AES测定硅、钾元素的释放浓度。结果表明,在振荡方式培养下,菌株AMCC10096在32 d内对钾的最大释放浓度为22.54 mg/L;AMCC10079在32 d内对元素硅的最大释放浓度为19.12 mg/L;在静置培养方式下,菌株AMCC10079在32 d内对钾的最大释放浓度为24.76 mg/L;菌株AMCC10079在32 d内对元素硅的最大释放浓度为20.28 mg/L;在尾矿处理过程中,选用静置培养的方法在32 d时间内更易促进钾、硅元素的释放,为尾矿的回收利用开拓了新的方向。
In this study, the bacteria density, p H value and the release of silicon and potassium in different culture conditions of AMCC10037, AMCC10079, AMCC10080 and AMCC10096 were studied. The contents of silicon and potassium were determined by ICP-AES Release concentration. The results showed that the maximal release concentration of AMCC10096 was 22.54 mg / L within 32 days under shaking culture, while the maximum released concentration of AMCC10079 was 19.12 mg / L within 32 days. , The maximum released concentration of AMCC10079 was 24.76 mg / L within 32 days. The maximum released concentration of AMCC10079 for elemental silicon was 20.28 mg / L within 32 days. During tailings treatment, Method is more likely to promote the release of potassium and silicon within 32 days, which opens up a new direction for the recovery and utilization of tailings.
