摘要: 云南某大型铅锌矿低品位氧化带的矿石含铅2.37%,含锌4.60%,铅、锌氧化率均高于90%,以往一直没有开采。为开发利用该矿石,对其进行了选矿试验研究。试验采用硫化—黄药浮铅和脱泥—硫化—新型胺类捕收剂KZF浮锌的工艺流程,取得了铅精矿铅品位39.92%,含锌5.18%,铅回收率61.31%,锌精矿锌品位37.03%,含铅1.23%,锌回收率67.29%的较好工艺指标。

Abstract: A large scale low grade oxidized lead-zinc mine containing 2.37% Pb and 4.60% Zn with a high ratio of oxidized lead-zinc ores reaching more than 90% has not been exploited.In order to utilize this kind of resources, an experimental study on beneficiation is carried out in which the process flow-sheets of sulfurization-lead floating with xanthate and desliming-sulfurization-zinc floating with amine collector KZF are adopted.A good technical index with 39.92% of lead concentrate containing 5.18% Zn at a Pb recovery of 61.31% and 37.03% of zinc concentrate containing 1.23% Zn and at a Pb recovery of 67.29% is achieved.
