Reverse Flotation. In reverse flotation of silica from iron ores using an anionic collector, Ca ions are introduced to adsorb on the silica and alter the surface charge to positive, thus enabling collector adsorption through the electrostatic mechanism (Houot, 1983). From: Wills' Mineral Processing Technology (Eighth Edition), 2016. Related terms:
