Two examples are the large low-grade ore bodies which requireSilver Gold Recovery Flotation Process,17.10.2016· Mechanically agitated machines have been found, on the whole, to give the best results with gold ores. The reason appears to be that free gold and some gold-bearing iron sulphides tend to float rather slowly, and vigorous agitation speeds up the flotation rate by intensifying their degree of flocculation. The “ Sub-A” Machine is employed more frequently than any other for this class of work.Gold Ore - an overview | ScienceDirect Topics,Flotation of arsenical gold ores associated with base metals is accomplished using a sequential flotation technique, with flotation of base metals followed by flotation of gold-containing pyrite/arsenopyrite. The pyrite/arsenopyrite is floated at a weakly acid pH with a xanthate collector.Gold extraction - Wikipedia,Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. 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 smeltedto for…
