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 NaSH provided the best results.

Advantages Of Using Gravity Concentration For Gold Recovery

Froth flotation and cyanide leaching both require costly reagents for optimal gold recovery. The type, ratio, and quantity of reagents needs to be optimized for every ore, and variability in the ore or poor reagent optimization can lead to poor recovery rates.

Gold extraction - Wikipedia

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.
