Research on mineral processing technology for the lead-zinc ore in the west of Sichuan

Dissemination character of the lead-zinc ore is complicated, the granularity of its mineral is different and the sphalerite consists of galena and chalcopyrite. The results of the experiment manifest that the lead-zinc ore is suitable for bulk flotation instead of single separation. On account of the low price and Yielding to demands from the user, we perform the experiment to separate the lead mineral and the zinc mineral and find whether a qualified single concentrate could be separated. The test consists of the detailed physical makeup research and the study on the separation of lead and zinc. By the technology such as bulk flotation-the second milling-the separation of lead and zinc, two products are obtained. One is the high quality lead concentrate which contains more than 65 percent of lead, the other is bulk concentrate which contains more than 55 percent of lead-zinc. This has advanced the commercial value of the lead-zinc ore.
