The Flotation Separation of Magnesite and Limonite Using an Amine Collector

In order to reduce the iron impurities in magnesite ore and improve purity of magnesium products, difference floatability between limonite has been studied by using mixtures with a collecting agent—KD (cationic amine collectors, containing soluble components). Sodium hexametaphosphate, pH, sodium silicate, carboxymethyl cellulose were used as regulators. Adsorption mechanisms reagents on minerals analyzed zeta potential analyzer infrared spectroscopy. silicate increased both at 11.6. All three regulators reduced minerals, while KD decreased limonite. likely chemically adsorbed surface minerals; electrostatic adsorption minerals.
