DZX-9捕收剂浮选冕宁低品位氟碳铈矿试验研究
Experimental Research on Flotation of the Low-grade Bastnaesite in Mianning Using the Collector of DZX-9
摘要
Abstract
The flotation of the bastnaesite type rare earth ore requires the flotation using the collectors of arbon hydroximic acid or modified hydroximic acid after desliming pretreatment to obtain the qualified bastnaesite concentrate. This kind of ore in Sanchahe Mianning Sichuan has the characteristics that the content of mud is high, the grade of REO is only 1.65% ,the bastnaesite is disseminated unequally and the mineral composition is very complex. The rough concentrate ( shorted as gravity concentrate ) with the grade of REO as 3.73 % obtained from low-intensity magnetic separation—gravity separation was chosen as the research object. The results show when the collector of DZX-9 was adopted,under the condition of that the value of pH is 8 ~9,sodium carbonate and water glass were acted as regulators, through one roughing, one scavenging and two cleaning, the closed-circuit flotation test can get the concentrate with the yield of 5.70% ,the REO grade of 60. 31% and the recovery of 92.16%. The technical index is good.关键词
