Froth flotation Wikipedia. Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Froth flotation of a Merensky Reef platinum bearing ore using mixtures in an attempt to improve concentrate grades and recoveries Theory and Practice. Volume 2: Flotation of Gold,
Process Introduction The flotation method is a widely used technique for the recovery of gold from goldcontaining copper ores, base metal ores, coppernickel ores, platinum group ores and many
platinumgroup metals (PGM) and gold from Stillwater Complex flotation concentrate. The Stillwater Complex is the only major PGM re#173; source. Development of a suitable extraction technique will contribute to its exploitation. The concentrate was roasted at 1,050#176; C to convert
1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air
Gold Flotation Production Line. Process Introduction. The flotation meth od is a widel y used technique for the recovery of gold from goldcontaining copper ores, base metal ores, coppernickel 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
Jul 23, 2014#0183;#32;The froth is removed from the top of the cell creating concentrated gold, while the flotation tailings at the bottom of the tank are disposed of. Thanks to froth flotation, miners and refiners are able to extract quality minerals from ore at lower grades than has been previously possible.
Though the gold recovery methods previously discussed usually catch the coarser particles of sulphides in the ore and thus indirectly recover some of the gold associated with these and other heavy minerals, they are not primarily designed for sulphide recovery. Where a high sulphide recovery is demanded, flotation methods are now in general use, but in the days before flotation was known, a
I claim: 1. In a froth flotation process for beneficiating a gold, silver or platinum group ore comprising slurrying liberationsized particles of said ore in an aqueous medium, conditioning the resultant slurry with effective amounts of a frothing agent and a collector, respectively, and floating the desired gold, silver or platinum group minerals by froth flotation methods, the improvement
flotation + Cyanidation. This method is most commonly used for goldcontaining quartz dike. Generally, the xanthate is used as the collector, and the terpenic oil is used as the ing agent, the gold concentrate is obtained from the weakly alkaline pulp in flotation machine.
A flotation method using mercaptobenzothiazole collector in an acid circuit was devised for preparing a platinumpalladium concentrate from Stillwater complex gabbro (Montana). Get Price Recovering Gold through the Froth Flotation ProcessMGS
However, froth flotation processes may also be used to concentrate the gold. In some cases, particularly when the gold is present in the ore as discrete coarse particles, a gravity concentrate can be directly smelted to form gold bars.

The flotation concentrate is filtered, bagged, and sent to a smelter (Bried et al., 2000). There are six gold mines in the Australasian region that treat refractory gold ores. The largest of these is the Porgera Gold Mine in Papua New Guinea, where a pyritearsenopyrite flotation concentrate is
