摘　　要：通过粒度分析、矿浆粘度和粉体ζ电位的测定,研究了六偏磷酸钠对黄铁矿超细粉碎的影响。分析了六偏磷酸钠与黄铁矿粉体的表面作用及黄铁矿粉体的界面作用能。结果表明,六偏磷酸钠能有效改善黄铁矿粉体在水中的研磨环境,显著降低矿浆表观粘度,提高粉碎效率。The influence of sodium hexametaphosphate on the pulverization of pyrite by stirred mill was studied through measuring the particle size, pulp viscosity and zeta potential. The surface effect of sodium hexametaphosphate on pyrite powders and the interface interaction of pyrite particles were analyzed. It was showed that the efficiency of ultrafine grinding of pyrite powders in water can be improved by the addition of sodium hexametaphosphate which can decrease the apparent viscosity of pulp and improve the grinding environment greatly.
