本研究的原矿含有10.17%Pb、10.98%Zn、57g/tAg和164g/tCd,取自土耳其开塞利省Aladag山脉的氧化铅锌矿山。预先浮选试验研究表明,锌回收没有选择性;因此,我们的研究主要集中在铅的选别。本次试验研究了以下因素对精矿铅品位和浮选效率的影响;浮选段数、Na2S和ZnSO4的用量以及浮选前的重选应用等。经过六段粗选和两次精选,采用350g/tKAX、250g/tAero407和4500g/tNa2S,得到的铅精矿铅品位和回收率分别为65.42%和77%,而且98.7%的锌留在尾矿中,其品位为12.23%。采用重选-浮选联合流程,得到的铅精矿铅平均品位为65.80%、总回收率为86.5%。在这两种流程里,锌都留在尾矿中,由于锌的矿物学结构复杂,不能够通过添加不同的药剂将其浮选回收,因此,提出采用冶炼的方法从尾矿中回收金属锌。
The ore from this study contains 10.17% Pb, 10.98% Zn, 57 g / t Ag and 164 g / t Cd from the lead-zinc mine in the Aladag range of Kayseri, Turkey. Pre-flotation test studies show that zinc recovery is not selective; therefore, our research has focused primarily on lead selection. In this experiment, the effects of the following factors on lead grade and flotation efficiency of concentrate were studied; the number of flotation sections, the amount of Na2S and ZnSO4, and the reselection and application before flotation. After six sections of rough selection and two times of selection, lead grades and recoveries of lead concentrate obtained by using 350g / t KAX, 250g / t Aero407 and 4500g / tNa2S were 65.42% and 77%, respectively, and 98.7% Mine, the grade of 12.23%. With the re-election - flotation process, the average lead content of lead concentrate is 65.80%, with a total recovery of 86.5%. In both processes, zinc remains in the tailings. Due to the complex mineralogical structure of zinc, zinc can not be recovered by adding different chemicals. Therefore, smelting is proposed to recover zinc metal from the tailings.
