摘　　要：对滇东北某铅锌矿锌铅硫混浮阶段进行了电位调控浮选试验研究,结果表明充气,添加氧化剂和外加电场等方式均能大幅提高黄铁矿的回收率。从经济和技术角度考虑,通过充气的方式来改善黄铁矿浮选的电化学环境是该矿下一步的工作方向。The experimental study on potential regulation for lead-sulfur bulk flotation of one northeast Yunnan ore was carried out,the results show,the methods,such as air inflation,oxidizing agent addition and external electric field addition and so on can greatly improve the recovery rate of pyrite.The air inflation method,which is used for improvement of electro-chemistry environment of pyrite flotation shall be the next step of work direction from the economic and technical considerations.
