The rougher concentrates went to a 6 ft. machine to make a final cleaned flotation concentrate. The mids from the cleaner machine were pumped back to be retreated in the.In the first part, flotation was adopted to separate galena from sphalerite rich sulphide ore. In the galena sphalerite flotation, aerofloat was used as the collector to replace xanthate, and Zn 2+ and SO 3 2− were combined to depress the sphalerite flotation.
Galena lead ore upgrading beneficiation Forui jig separator . Lead usually exists in pattern of intergrowth with Zinc like the common lead zinc ore. And the floatation separation is usually used for this kind of lead ore while sometimes gravity separation or gravity floatation separation is needed to upgrade this kind of lead ore.Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
