摘要
针对辽宁某钼矿浮选中,水玻璃用量大,尾矿沉降及tfqp矿水回水困难问题,研制了可在低水玻璃用量条件下,对该钼矿实现有效分选的新型捕收剂DT-1。实验结果表明:新型捕收剂DT-1对辉钼矿具有很强的捕收能力和较好的选择性,与传统煤油、黄药等捕收剂相比,DT-1在减少60%水玻璃用量的情况下仍然可以获得较好的指标,经过闭路试验,最终得到了品位为53.04%,回收率为95.02%的钼精矿。
The new type collector DT-1 which is good at flotating molybdenum was made and investigated for aiming at gangue being difficult to sediment and water using in flotation being difficult to reuse because of a lot of dosage of sodium silicate in a molybdenum flotation of Liaoning province.The results show that the collector DT-1 has stronger collecting power and well selectivity for molybdenite.Compared with traditional kerosene and xanthate flotation,this process using the new collector could have a good index with 60% sodium silicate.The closed-circuit test results are as follows：the molybdenum concentrate of 53.04% with the molybdenum recovery of 95.02% is obtained.
