Flotation 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.
Mar 25, 2020 The gold flotation process can not only enrich maximum gold into the sulphide mineral concentrate, but also discard the tailings, so the processing cost is low. Besides, the gold flotation process can also be used to polymetallic gold mining, such as gold-copper, gold-lead, gold-antimony, gold-copper-lead-zinc-sulfur ores.
Gold Flotation Production Line. Process Introduction. The flotation meth od is a widel y 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 ...
Jan 01, 2016 1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors specifically xanthates and dithiophosphate collectors that allowed differential flotation of sulfide minerals Weinig and Carpenter, 1937, Rabone, 1939, Richards and Locke, 1940, Taggart, 1945.
Dec 20, 2018 The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons 1 In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of
The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
Gold processing - Gold processing - Mining and concentrating The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade e.g., 3 to 10 parts per million that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
