Froth flotation - Wikipedia

Illustrative, the flotation process is used for purification of potassium chloride from sodium chloride and clay minerals. The crushed mineral is suspended in brine in the presence of fatty ammonium salts. Because the ammonium group and K have very similar ionic radii (ca. 0.135, 0.143 nm respectively), the ammonium centers exchange for the surface potassium sites on the particles of KCl, but not on the NaCl particles. The long alkylchains then confer hydrophobicity, to the particles, which enable them to form fo

Froth Flotation of Iron Ores

02/01/2012  The flotation routes of iron ore can be classified into five major groups, i.e. cationic flotation of iron oxide, cationic flotation of quartz, anionic flotation of iron oxide, anionic flotation of quartz, and combination[2]. Despite the variety of flotation routes developed for iron ores, currently, the reverse cationic flotation route developed by the USBM branch in Minnesota is by far the most widely used flotation route in the iron ore industry. The two anionic flotation
