摘要
本文从理论上简单分析了采用真空冶金法处理脆硫铅锑矿分离铅与锑新工艺的可行性,并对该新工艺中影响铅与锑分离效果的温度、时间等因素进行了讨论。试验研究表明采用真空冶金的方法处理脆硫铅锑矿可以实现铅与锑的一步分离,获得高质量的铅精矿和锑精矿。对比目前主流处理方法可以看出该新工艺可以缩短整个处理流程,提高资源的利用,符合低碳、高效冶炼金属的要求。
A novel environmental firendly techniquie was developed to separate lead and antimoney from Jamesonite by vacuum evaporation. The impacts of the distillation conditions, such as the distillation temperature and time, pressure, and energy consumption, on the separation rates of lead and antimony were experimentally investigated. The contents of the condensed volatiles and slag were characterized with X-ray diffraction, and conventional chemical analysis. The preliminary results show that the newly-developed vacuum distillation is feasible to separate lead and antimony from jamesonite, and that the distillation temperature and time have a major impact on the separation. For example, at a distillation temperature ranging from 1200℃ to 1400℃ ,theseparation rates of lead and antimony were found to be higher than 99%. Besides, an increase of distillation time also weakly increased the separation rates. The multistage condenser is capable of enriching lead and antimony, respectively. The advantages of the novel technique over the conventional one on industrial scale were also tentatively discussed.
