本文研究了弱极性非离子型添加剂在硫化矿絮凝 -浮选和氧化矿浮选中的应用。氯代烷烃与黄药合用或ИДС与油酸钠合用 ,可在适宜pH值和使用调整剂时 ,提高矿物优先浮选指标。硫化矿物分选指标的提高主要是由于细粒矿物的絮凝 ,而氧化矿物浮选分离指标的提高主要是因为油酸钠在矿物上吸附层密度的差异增大所致
In this paper, the application of weakly polar nonionic additives in flocculation and flotation of sulphide ore and flotation of oxide ore has been studied. Combined use of chlorinated paraffins and xanthate or ИДС in combination with sodium oleate enhances the mineral’s preferred flotation index at appropriate pH and use of conditioning agents. The improvement of sulfide mineral separation index is mainly due to the flocculation of fine-grained minerals, while the increase of the index of flotation of oxidized minerals is mainly due to the increase of the difference of the density of sodium oleate adsorbed on minerals
