摘    要:针对青海某铜铅锌多金属硫化矿石易浮难分、有用矿物嵌布粒度极不均匀的特点,采用铜、铅、锌依次优先浮选工艺流程及特别研制的新型捕收剂YK1-11和新型抑制剂YK3-09对其进行选矿试验,并在选铅时采取反浮精选措施,获得了铜品位和铜回收率分别为18.02%和57.50%的铜精矿、铅品位和铅回收率分别为51.43%和33.20%的铅精矿、锌品位和锌回收率分别为45.83%和48.95%的锌精矿以及Pb+Zn品位为69.99%,铅、锌回收率分别为42.56%和34.05%铅锌混合精矿,并使矿石中的伴生银得到了有效富集,为合理开发利用该矿石提供了依据。

关 键 词:铜铅锌多金属硫化矿    优先浮选    新型捕收剂YK1-11    新型抑制剂YK3-09    铜反浮精选

Abstract:In view of characteristics of easily-floating and uneven distribution of valuable minerals for a poly-metallic Cu-Pb-Zn sulfide mine in Qinghai,the beneficiation tests were carried out by process of prior flotation of copper,lead and zinc in turn with new-type special collector YK1-11 and new-type inhibitor YK3-09. And the inverse flotation was adopted in lead concentration. Then,copper concentrate with Cu grade of 18.02% at a 57.50%recovery,lead concentrate with Pb grade of 51.43% at a 33.20% recovery,zinc concentrate with Zn grade of 45.83% at a 48.95% recovery,Pb-Zn concentrate mixture with Pb and Zn grade of 31.53% and 38.46% at a 42.56% Pb recovery and 34.05% Zn recovery were respectively achieved. Also,the associated silver in ores was effectively enriched,thus providing a basis for rational exploitation of the ores.
Keywords:Poly-metallic Cu-Pb-Zn sulfide mine  Prior flotation  New-type collector YK1-11  New-type inhibitor YK3-09  Inverse flotation of copper
