摘要
讨论了羧甲基纤维素作为调整剂用于低品位萤石矿的分选问题,分析了矿石性质、制样过程和磨浮工艺,确定了浮选最佳工艺参数.在磨矿细度-200目占80%、浮选温度26℃~35℃、油酸用量600~650g/t矿、羧甲基纤维素用量600g/t矿,硫酸用量300g/t矿参数条件下,采用一粗六精中矿集中返回工艺,萤石精矿品位可达到98%以上,回收率可达到88%以上.
grade fluo discussed, arboxymethylcellulose is utilized as regulator and applied to the separation test of low te. The characterization of mineral, sample preparation, grinding-flotation process are and the optimal floating parameters are obtained. mesh grinded ore fineness accounts for 80%, dosage is 600-650 g/t, g/t, more than 98G of chieved by adopting the culation. carboxymethylcellulo concentrate grade flowsheet of one r , floatation se dosage is tern Under the condition of that -200 perature is 26℃-35℃, oleic acid 600 g/t, and sulfuric acid dosage is 300 and 88% of recovery efficiency of fluorite could be a oughing, six cleaning, and concentrated middling recir
