• Gold Flotation - Mineral Processing Metallurgy

    Cyanidation is usually the most suitable process, but it often necessitates grinding ore to a fine size to release the gold and silver. Where it is possible to obtain a good recovery by flotation in a concentrate carrying most of the pyrite or other sulphides, it is often more economical to adopt this method, regrinding only the comparatively small bulk of concentrate prior to the leaching ...

  • Extraction of Gold by Flotation Process

    Gold is an easy-floating mineral, so extraction of gold by flotation process has always been one of the effective ways to process gold-bearing ores. In primary gold deposits, gold minerals often coexist with sulfide minerals such as pyrite, chalcopyrite, galena, and sphalerite. These minerals are both easy-floating minerals and form stable mineralized foams. They are the ideal carrier minerals ...

  • Optimisation of gold recovery by selective gold flotation ...

    Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative treatment route for gold room applications where ...

    If the gold is in the form of gold sulfide, its floating behavior is equivalent to sulfide ore, and sulfide ore containing gold after the floatability generally have increased. To sum up, the ore in the gold has both easy to float side, but also has a difficult floating side. In order to fully recover in the actual production process, we should take appropriate measures based on above ...
