effect of reverse flotation on magnetic separation concentrates

aug 9 abstract reverse flotation studies on magnetite samples have revealed that the use of starch as a depressant of fe-oxides has a hydrophilic effect on the surface of fe-bearing silicates and significantly decreases fe in the silica-rich stream when used in combination with an amine lilaflot dm in this
