Jul 13, 2016· GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
The flotation cyaniding method is the most important process among the whole, silver concentrate can be got in the process of flotation, then regrinding to the next process including cyaniding and leaching, countercurrent washing, zinc powder replacement, silver ingot can be finally got after electrolytic dissociation.
Oct 17, 2016· A total recovery of more than 97% of the gold and silver is made by flotation, while the combined flotation cyanidation process gives an overall
The present invention is directed to flotation of refractory gold sulfide ores in which the ore is ground, floated, the tailings reground, and refloated to produce gold bearing concentrates. Process for recovering gold and silver from refractory ores
