浮选指标的高低与浮选药剂密切相关。浮选药剂的品种、质量,不但对浮选工艺发展有重要作用,而且对选矿指标,节省原料,降低生产成本也有直接影响。我国浮选药剂品种少,单位消耗高。黄药一直是最重要的硫化矿浮选捕收剂,品种也仅限于乙基及正丁基黄药。在目前丁醇供应紧张、正丁基黄药短缺的情况下,增加黄药品种,推广使用新药剂,既可改变黄药生产依赖 The level of flotation index and flotation reagents are closely related. The variety and quality of flotation reagents not only play an important role in the development of flotation process, but also have a direct impact on dressing index, raw material saving and production cost reduction. China’s flotation less varieties, high unit consumption. Xanthate has been the most important sulphide flotation collector, the species is limited to ethyl and n-butyl xanthate. In the current shortage of butanol supply, n-butyl xanthate shortage, the increase of xanthate varieties, promote the use of new agents, both can change the xanthate production dependence
