Jul 20, 2015· Fluorspar tailings produced at Vergenoeg Mine contain a substantial amount of haematite. Reverse flotation of haematite from the tailings has been investigated using a batch, bench -scale mechanical cell. Characterisation of the fluorspar tailings was done and effects of various operating parameters on the recovery of haematite were studied. The …

The prediction of the amount of sulfur removal in the reverse flotation of iron ore concentrate is an important issue to enhance the process efficiency. When the sulfur content of iron concentrate increases, the sulfur recovery and efficiency will reduce. In this situation, the operators at concentrators try to identify the problem and find a ...

The reverse flotation of iron ores is the usual process for the beneficiation of iron ores. In this case the silica particles are floated with amines. Usually this pulp, including the main part of amines, is deposited in the tailing dams. In the best case a part of the amine free water is reused as process water after a long residence time.
