摘要: 四川省某低品位铅锌矿矿石因氧化程度高、矿物嵌布粒度细、易泥化等特点,尤其是矿石中含有大量的赤、褐铁矿,而锌矿物以菱锌矿为主,且品位低,回收难度极大,此类矿石常被视为呆矿。本试验针对矿石特性按照阶段磨矿、优先浮选的原则流程,在传统的硫化浮选工艺基础上,采用组合捕收剂L-05选别氧化锌矿,最终获得了铅品位和回收率分别为50.22%和76.25%、含锌1.89%的铅精矿及锌品位和回收率分别为20.01%和56.14%、含铅1.52%的锌精矿,成功实现了氧化铅锌矿石的有效分选。

Abstract: A low grade Sichuan lead-zince ore is characterized by s high oxidation, fine dissemination size and easy sliming and especially a large amount of hematite and limonite. Its main zinc mineral is smithsonite, which is of low grade and extremely difficult to recover. Such type of ore is often abandoned. Test was made in light of the ore properties, where a principle process of preferential flotation and two staged grinding was adopted. Based on the conventional sulfuration-flotation, a compound collector of L-05 was used for zinc oxide ore. As a result, a lead concentrate with 50.22% lead grade, 76.25% recovery and 1.89% zinc content, and a zinc concentrate with 20.01% grade, 56.14% recovery and 1.52% lead content were obtained, realizing an effective separation of lead from zinc of oxide ore.
