为了提高岩盐伴生性钙芒硝矿进行资源化利用效率,对取自盐化制碱厂的淡钙液与钙芒硝矿进行了溶解反应试验,以测试钙芒硝与淡钙液的反应速率,并提出一定条件下钙芒硝与淡钙液的理想反应量。通过恒温40℃条件下,钙芒硝与去离子水、硝性近饱和卤水、钙性卤水进行一系列溶解对比试验,发现当钙性卤水中主要离子浓度比Na+:Cl-:Ca2+为1:3.37:1.03时,为最佳溶解组分配比,其最大溶解速率为54.689 g/(m2.h),溶解速率与Na2SO4浓度关系曲线拟合方程y=-8.482Ln(x)+57.362,相关系数R2=0.895。试验结果为探讨研究在岩盐伴生条件下钙芒硝溶解转化利用的最佳开采方案提供依据。
In order to improve the efficiency of resources utilization of rock salt-associated glauberite miners, the reaction of light calcium and glauberite miners from salinization plant was carried out to test the reaction rate of glauberite with light calcium solution and put forward Under certain conditions, the ideal reaction amount of glauber’s salt and light calcium solution. A series of dissolution comparison experiments of glauberite with deionized water, near-saturated nitric brine and calcium brine by constant temperature 40 ℃ found that when the main ion concentration in calcium brine is 1: 3.37 Na +: Cl-: Ca2 + : 1.03, the maximum dissolution rate was 54.689 g / (m2.h), the dissolution rate was related to the concentration of Na2SO4 curve fitting equation y = -8.482Ln (x) +57.362, the correlation coefficient R2 = 0.895. The results provide the basis for exploring the optimal mining scheme for dissolving and transforming glauberite under rock salt-associated conditions.
