随着浮选生产实践及浮选理论研究的进展,对硫化矿天然可浮性及无捕收剂浮选的研究也正在蓬勃兴起。一、研究概况 Lepetic(1974年)采用干式自磨获得黄铜矿石粉,加入PH6.1—6.6的水中,用7种起泡剂分别进行了无捕收剂浮选试验,结果都能获得比较高的回收率,其中有的比有捕收剂浮选结果还好。他认为,单用起泡剂浮选黄铜的可能原因是:在缺少水或无水的 With the development of flotation production practice and flotation theory research, the research on natural flotation and non-collector flotation of sulfide ore is also booming. First, the research overview Lepetic (1974) obtained by dry self-grinding chalcopyrite powder, added to the PH6.1-6.6 of water, with seven kinds of foaming agent were collector-free flotation test, the results can be obtained Higher recoveries, some of them better than collector flotation results. In his opinion, the possible reasons for flotation of brass with a blowing agent alone are: lack of water or water
