Gold Flotation - 911 Metallurgist

13/07/2016  The commonly used promoters or collectors are “Aerofloat” reagents and the xanthates. The most effective promoter of free gold is Aerofloat flotation reagent 208. When auriferous pyrite is present, this reagent and reagent 301 constitute the most effective promoter combination. The latter is a higher xanthate which is a strong and non-selective promoter of all sulphides. Amyl and butyl

Gold Flotation Gold Mining Process Gold Mining ...

The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores, base metal ores, copper-nickel ores, platinum group ores and many other ores where other processes are not applicable. Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment, for the upgrading of low sulfide and refractory ores for further treatment. Flotation is considered to be the most cost-effective method for concentrating gold ...

Silver Gold Recovery Flotation Process - 911 Metallurgist

17/10/2016  Sodium diethyl-dithiophosphate, is one of the most successful promoters for the flotation of free gold, while their Reagent “ 301 ”, a higher xanthate mixture, has been found specially useful for gold-bearing pyrite; sodium aerofloat and amyl xanthate are sometimes employed in place of or in conjunction with them. Flotation is generally carried out in a pulp with a pH value of 7 .0-7 .5, soda

Froth Flotation and Gold Extraction - Manhattan Gold

23/07/2014  In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity. First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water. Air bubbles are pumped into the flotation ...
