一绪言日本小坂矿业公司内之岱选矿厂,把铜铅全浮选泡沫产品加温至70℃,可不用任何抑制剂而进行有效的铜铅分离。以此法代替历来沿用氰化钠分离法后,不仅使选矿成绩大幅度提高,而且在环境保护上,对于根绝氰化物造成的废水污染亦卓著成效,前已有报道。但是,对于这种现象的理论依据,因当时的知识水平 INTRODUCTION Daisen Mining Co., Ltd. in Japan, Dai beneficiation, the copper and lead flotation foam products warmed to 70 ℃, without any inhibitor for effective separation of copper and lead. This method instead of always using sodium cyanide separation method, not only to make a significant increase in beneficiation results, but also in environmental protection, the elimination of cyanide-induced wastewater pollution is also remarkable results, has been reported before. However, the theoretical basis for this phenomenon, due to the prevailing knowledge level
