国外某铅、锑复杂矿石中主要金属矿物为脆硫锑铅矿及黄铁矿，矿石中的伴生金主要赋存于脆硫锑铅矿中，其次赋存于黄铁矿中。矿石锑品位1.50%，铅品位2.21%，金品位5.1 g/t，对矿石进行选矿提取预富集，有效地回收矿石中各有价金属。此外，对选矿预富集所得的产品的冶炼加工技术进行了探讨。
The minerals of a lead-antimony complex ore from abroad are predominately jamesonite and pyrite, with gold in its native state predominately disseminated in jamesonite and secondarily in pyrite. The ore with 1.50% grade of antimony, 2.21% lead and 5.1 g/t gold, according to beneficiation extraction and preconcentration, effectively recover all valuable mineral, maximize using the mineral value.
