The flotation of gold bearing ores — A review - ScienceDirect

01/07/1994· 01/07/1994· FLOTATION CELLS AND CIRCUITS The most interesting and important application of new flotation cells for gold flotation is the Skim Air [Flash] flotation cells especially in a flotation plant where the tailings are not cyanide leached (e.g. 846 c.T. O'CONNOR and R. C. DUNNE copper-gold ores). The high relative density of gold and some gold minerals means that they areleaching in gold flotation separation of mining new,leaching in gold flotation separation of mining new.
