摘 要：用改进的挂槽式浮选机研究了纯金粉在不同条件下的可浮性,重点考查了电位对金粉可浮性的影响,得到了最佳的浮选条件：电位(SHE),pH＝9.0和[Na2S]＝10－4～10－3mol/L.实验结果表明,纯金粉也具有较好的硫诱导电化学调控可浮性.
Abstract: The flotability of gold has been determined in laboratorial flotation tests with a modified flotation bath. The effects of pH value, the concentration of Na2S and especially, the potential of gold on the flotation recovery have been investigated. The optimal flotation conditions are pH=9.0, [Na2S] =10-4～10-3 mol/L, (SHE). It has been concluded that gold powder is of sulfur-induced electrochemical control flotatbility.
