Reverse column flotation of iron ore | SpringerLink

2007-5-1 · The use of column flotation was considered for the “reverse flotation” of iron ore, where the gangue (quartz) was recovered in the froth product. This use of the froth for carrying the gangue mineral rather than carrying the valuable concentrate significantly changes the operational requirements of the column. The objective of this work was to determine which of several column flotation ...

An overview of the beneficiation of iron ores via reverse ...

Abstract. Flotation is the most effective solution, both technologically and economically, when upgrading iron concentrates. Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica ...

Impurity Removal in the Reverse Flotation of Iron Ore

Vale is the largest iron ore producer in the world. Since the 1970s, Vale has been using reverse cationic flotation to remove siliceous impurities from its iron ores. Whilst this flotation process has operated effectively for many years, it suffers from the problems of high reagent costs and high metal loss.In 2010, CSIRO investigated the use of a reverse anionic flotation process for Vale ...

When the test sample contains relatively lesser gangue, it is easier to float it and hence reverse flotation can be employed rather than direct flotation where in major proportion of the material, otherwise, would have to be floated. As such, the reverse flotation is the usual process for the beneficiation of iron ore slimes.

Froth Flotation of Iron Ores - CSIRO Publications

the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.
