Examples of industrial sulfate precipitation technologies comprise the SAVMIN and CESR (cost effective sulfate removal) processes, the integrated lime/limestone process and the BaS process [4]. The main advantage of all precipitation processes is the familiarity of the mine industry with this unit operation whereas the …

In a limestone mine, a large amount of slime is washed off in order to remove impurities such as clay minerals. A fine sized calcite is, consequently, wasted and freight for carring the slime to reclaim land is expensive. The separation of calcite from the slime has been investigated by the flotation process, using sodium oleate as a collector. A satisfactory …

We examined the primary mechanisms controlling water quality evolution in the Carboniferous aquifer in the Yangzhuang coal mine (Huaibei coalfield). Q-mode factor analysis explained how the Na+ and SO42− concentrations gradually increase and the hydrochemical type transforms from Ca-HCO3 to Ca·Na-HCO3 and Ca·Na-HCO3·SO4 …
