【摘要】 进行了不同模数的水玻璃应用于云南某磷矿浮选的研究,通过浮选试验结果的比较以及水玻璃在浮选过程中的溶液化学行为分析,探讨了液碱法生产的低模水玻璃在胶磷矿正反浮选生产中应用的可行性。实验结果表明:虽然高模、低模水玻璃在模数、硅酸钠含量及所形成金属硅酸盐的溶度积等方面有所差异,但浮选溶液化学理论计算结果显示二者在同样用量情况下调节溶液pH、抑制脉石的能力基本一致。更多还原

【Abstract】 According to the study results of sodium silicate with different modulus applied to phosphor Mine in Yunnan province and the results of flotation test,as well as the results by analysis of the chemical behavior of sodium silicate in solution,the possibility of application of low modulus sodium silicate produced by liquid alkali process,in collophanite`s direct-reverse flotation process was studied.Our study showed that although differences existited between high and low modulus in the contents of sodium silicate and solubility products of silicate,the ability of both modulus in control the solution’s pH value and inhibitor gangue wer the same.更多还原
