Beschreibung
Zusammenfassung:	The present invention relates to RE mineral floating process and is one bastnaesite floating process. The bastnaesite floating process includes eliminating mud while adding dispersant, mixing size and floating separation. During floating separation after mixing size, water glass, hydroximic acid as main catching agent, L108 as supplementary catching agent and foaming agent are added successively;the ore slurry density, pH and temperature are controlled, and once or twice separations are performed to obtain high-grade RE concentrate. The present invention has short process, high grade, high recovering rate, low chemical consumption, low cost and easy deposition of tailing mud water.
