Flotation of Gold and Gold-Bearing Ores - ScienceDirect

2016-1-1  A recent study of a number of flotation plants found that floated gold grains in the concentrate had a greater concentration of silver and sulfur than the gold remaining in the tailings, implying that they assisted gold flotation (Chryssoulis, 2001). Laboratory flotation tests on a flotation-plant tailing sample using NaHS and silver ions recovered 30–45% of the unfloated gold and NaHS provided the best results.
