Reverse Flotation

Reverse flotation of coal can be explained as a process where valuable minerals are depressed, while undesired and unhealthy minerals are floated with the help of some reagents , In their experiment, clean coal with 7% ash and silica were mixed as a feed, and quantity of each element was same From the results of experiments, reverse .After a reverse froth flotation step, generally the iron ore bottom fraction either contains a low level of silica but exhibits a low recovery of iron, or it exhibits high recovery of iron but contains a high level of silica.

Reverse flotation of hematite from a local silica sand ore has been investigated using a batch, bench scale mechanical flotation cell Samples of silica sand with known measured size distributions were mixed with tap water and the required amount of Aero 800 collector and acid added to the mixtureMar 22, It is a type of flotation known as "reverse flotation", since the tailings (quartz or silica particles) are floated, and the desired ore, namely phosphate rock particles, sink and become the concentrate The silica is, in fact, present in a much greater amount than the phosphate rock.
