In over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore., but blending depressants is not a common practice. The use of a combined reagent system could render the depressant action more selective and efficient, besides providing a higher recovery of fine particles, which impair the selectivity. Under this scenario, polyacrylamides are an option to be studied as a co-depressant in iron ore flotation.depressants for the depression of iron oxides through the traditional reverse flotation.CA1328512C CA000582253A CA582253A CA1328512C CA 1328512 C CA1328512 C CA 1328512C CA 000582253 A CA000582253 A CA 000582253A CA 582253 A CA582253 A CA 582253A CA 1328512 C CA1328512 C CA 1328512C Authority CA Canada Prior art keywords flotation mineral iron depressant gangue Prior art date 1987-11-04 Legal status The legal status is an assumption and is
