为了研究各种絮凝剂和凝聚剂对克里沃洛格矿区各选矿厂微粒铁精矿脱水效果的影响,试验了熟石灰、生石灰、硫酸、在国外应用的一些絮凝剂(57、60、80、116和183)、聚丙稀酰胺、(已二胺残液、塔尔油和二氯乙烷的冷凝产物)、(蒸馏塔尔油皂)及在不同条件下配合成的各种混合物。研究表明,石灰和酸对固体颗粒沉降过程有一些改善,但很不够。熟石灰比生石灰的作用较为有效。在所使用的外国生产的五种絮凝 In order to study the effect of various flocculants and flocculants on the dehydration effect of various iron ore concentrate concentrates in the Kliwall mining area, hydrated lime, lime and sulfuric acid were tested. Some flocculants used abroad (57, 60, 80, 116 and 183), polyacrylamide, (residues of diamine residues, condensation products of tallow and dichloroethane), (distillate soap), and various blends formulated under different conditions. Research shows that lime and acid have some improvements in the settling of solid particles, but not enough. Ripe lime is more effective than quicklime. Five types of flocculation are used in the foreign production
