Take A LookFlotation is one of the most widely used methods to process gold ores, especially suitable for sulfide gold ores with high reproducibility. This method is suitable for processing gold-bearing sulfide ores with fine gold particles and good flotability. In the flotation process, sulfide ores are enriched in sulfide concentrates as gold carriers.
Take A LookFlotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
Take A LookFlotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.
Take A LookFor vein gold ore with high arsenic and sulfur or high carbon argillaceous, the gold sulfide concentrate can be obtained by the froth flotation, and then the flotation concentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly sophisticated gold extraction method with low toxicity.

Take A LookJan 24, 2014· Floating gold using flotation methods has been studied and tested by people who understand flotation, bubble angles and the whole 9 yards of the science of flotation and no one does this commercially because it works very poorly. The gold does not stay attached to the bubble in the froth of a flotation cell.
Take A LookJul 23, 2014· Froth Flotation and Gold Extraction. Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
Take A LookMar 14, 2016· Flotation method is more popular with large-scale miners although it is also used by artisanal miners. This is the perfect method for processing gold found in complex materials. The flotation method involves mixing your crushed ore with water and then you add frothing agents in a single floatation machine.
