摘　　要：介绍对难选氧化铅锌矿用新的联合法富集,即先用元素硫在水热条件下使氧化矿物硫化,然后用普通浮选法对人造硫化矿进行浮选。So far there＇ s been no plenty of low-grade oxidized lead-zinc ore to be used, because of its complex mineral compo- sition, the useful minerals associating tightly with gangue, the surface of the objective mineral accompanying by other mineral films or cov- ered with other minerals, and low content of the useful metals in raw ore. These adverse factors result in great loss of the objective minerals with tailings. The refractory oxidized lead-zinc ore can be enriched by the following new combination method ： firstly, the oxidized minerals were sulphidized with sulphur under hydrothermal condition ; then the flotation of the artificial sulphide ores were carried out.
