Flotation Machines Mineral Processing Machine

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.

Results were achieved from an initial composite feed grade of 0.401% V2O5, prior to graphite extraction through flotation. A full-scale commercial circuit could employ more stages of cleaning and scavenging, and intermediate products such as cleaner tailings and scavenger concentrates could be recycled to achieve improved concentrate grades and recoveries.

What is the role of depressant in froth floatation process?

What is the role of depressant in froth floatation process? Answer. In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with
