RESEARCH ON SEPARATION OF MAGNESITE AND DOLOMITE BY FLOTATION USING DODECYL PHOSPHORIC ACID ESTER AS A COLLECTOR

In the experiment, an anionic surface active agent-dodecyl phosphoric acid ester is synthesized with-dodecanol, phosphorus oxychloride and the other materials. The collective power of dodecyl phosphoric acid ester on magnesite and dolomite has been researched, and with help of water glass as a modifierthe possibility and conditions of separating magnesite and dolomite using dodecy1 phosphoric acid ester as acol1ector by flotation have been investigated.
