摘　　要：在实验室条件下对影响硫精矿滤饼水份的原理进行了研究。研究表明大冶铁矿分离浮选所用的药剂对硫精矿的脱水过程有影响 ,影响硫精矿滤饼水份的主要因素是分离浮选中作为黄铁矿抑制剂使用的石灰 ,同时Z - 2 0 0 #捕收剂对硫精矿的滤饼水份也有不利影响 ,但其影响程度比石灰要小。用硫酸调节硫精矿矿浆的 pH值可以降低其滤饼水份。Laboratory study was made on the mechanism of influencing the filter cake moisture of sulfur concentrate.The results have shown that the flotation reagents used for separation in Daye Iron Mine do have an effect on the dewatering of sulfur concentrate.The main factor that influences the filter cake moisture is the lime used for depressing pyrite in flotation and Z-200 # collector also has an unfavourable effect but less than that of the lime.Regulating the pH value of the sulfur concentrate pulp with sulfuric acid can reduce the filter cake moisture.
