摘要
论述了KF－102是大冶铁矿硫精矿有效的一种助滤剂，其适宜用量135g／t。作用机理是KF－102可使滤饼比阻降低，减弱了水化膜的影响，进而降低了滤饼的水分。同时它能改善滤饼结构，使得滤饼中物料粒度分布均匀，并使滤饼孔隙度增加了2．5个百分点，提高了过滤速度。
With an appropriate dosage of 135 g/t, KF-102 acts as an efficient filtration aid for Daye Iron Mine's sulphur concentrate. Its mechanism lies in that it can reduce the specific resistance of the filter cake and weaken the effect of water film so as to reduce the cake moisture. Meanwhile, it may improve the cake structure, make even the size distribution of the material in the cake and increase the cake porosity by 2. 5%. As a result, the filtration rate increases.
