Flotation of Gold and Gold-Bearing Ores - ScienceDirect

2016-1-1  Concentrators that have this circuit configuration have found that most of the fine gold is recovered in the flash flotation circuit, leaving the gravity circuit to recover the coarser gold. One of the dilemmas arising from laboratory testing for the combined circuit is that the standard gravity test procedure will overpredict plant gravity recovery, because fine free gold is captured in the laboratory test.
