摘要/Abstract

摘要： 滇池周边拥有巨量的中低品位磷矿资源，为了高效开发这些资源，并解决磷矿石浮选常规捕收剂常温下分散性和溶解性差的问题，用昆明冶金研究院研制的新型常温捕收剂CL-07+CJ，对滇池附近某磷矿石进行了选矿试验。结果表明，该矿石在磨矿细度为-200目占60.4%，浮选温度为15 ℃，脉石矿物抑制剂Na2SiO3粗选用量为2.0 kg/t，矿浆pH调整剂NaOH粗选用量为0.8 kg/t，磷矿物捕收剂CL-07+CJ粗选用量为0.4+0.14 kg/t情况下，采用1粗2精1扫、中矿顺序返回流程浮选，可获得P2O5品位为34.60%、P2O5回收率为94.10%的磷精矿。

Abstract: There are huge amount of middle-low grade phosphorite rock resources around Tien Lake.In order to high-efficiently exploit these resources and solve the problems such as poor decentrality and solubility of traditional collectors，beneficiation experiments on a phosphorite around Tien Lake was carried out by using a new type collector CL-07+CJ invented by Kunming Metallurgical Research Institute.The results showed that phosphorus concentrate with P2O5 grade of 34.60%，P2O5 recovery of 94.10% was obtained with the grinding fineness of 60.4% passing 200 mesh，slurry temperature at 15 ℃，dosage of gangue mineral depressor Na2SiO3 of 2.0 kg/t and slurry pH regulator NaOH at 0.8 kg/t for roughing，dosage of phosphate mineral collector CL-07+CJ at 0.4+0.14 kg/t，through process of one roughing-one scavenging-one cleaning，middles back to the flow-sheet in turn.
