Gold Flotation - 911 Metallurgist

13/07/2016  REAGENTS USED IN FLOTATION OF GOLD ORES. Conditioning agents are commonly used, especially when the ores are partly oxidized. Soda ash is the most widely used regulator of alkalinity. Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold.

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

01/01/2016  At the Royal Oak Mine in Ontario, Canada, the predominantly pyritic gold ore was treated by flotation to produce a concentrate that was reground to 38 mm before preaeration and cyanide leaching. Flotation reagents were PAX, dithiophosphate, and Dowfroth 250 (Bedard et al., 2000).

Sulphide Gold Ore Treatment by Leaching and Flotation

18/04/2016  The calcine is then quenched, ground and returned to the plant. In fact, flotation has made possible the treating of such ore bodies for the recovery of gold. It was never possible to treat these direct by cyanide and difficult to roast ore alone because of the large amount of extraneous heat required. Flotation concentrates are usually self-roasting. One particular plant uses a flowsheet similar to No. 2. Here flotation concentrates are reground. The flotation
