| Abstract: |
| A large sulfide lead-zinc deposit in Guangdong Province is famous for its mineral processing technical difficulties and unique geological phenomenon. The new process technology is investigated through systematic mineralogical studies to ascertain the causes of its refractory and analyzed and summarized the previous existing technologies and useful experience. Since some fine particles are disseminated within pyrite, the conventional methods fail to dissociate the ores. Aimed at this feature, priority floatation process was used in the research by creatively introduction of ultrafine grinding milling, the dislocation degree of the middlings has increased significantly, resulting in the effective enhancement of the recovery rate of lead. At the same time, considering that the traditional method of high alkali inhibition on pyrite having caused has many production problem, a new environmental organic small molecular inhibitors QS was used partially replacing lime, and superior beneficiation indexes have been obtained. |
