Proline Gold Mining and Prospecting Equipment/Gold Dredges
When other " dredges were floating on innertubes, required a suction nozzle for producing dredge vacuum, and had limited depth capabilities, the Proline " dredge sat on sturdy pontoons and used a power jet for dredge vacuum. It was also capable of driving an air compressor to support more active underwater mining.
Extraction of Gold by Flotation Process
· · Gold is an easyfloating mineral, so extraction of gold by flotation process has always been one of the effective ways to process goldbearing ores. In primary gold deposits, gold minerals often coexist with sulfide minerals such as pyrite, chalcopyrite, galena, and sphalerite.
