Process for separation of bastnaesite from weathered bastnaesite barite fluorite ores |
| abstract |
The present invention provides a process for the recovery of bastnaesite and other minerals containing rate earth oxide from complex, weathered ores containing barite, borite, fluorites and/or barite, fluorites, silicates and iron oxides, and comprises reverse barite flotation using a barite collector containing the following individual reagents: n n n n n n n n n n n n 1. Petroleum sulphonate n 30-40% by weight n n n 2. Sulphosuccinate n 30-40% by weight n n n 3. Sulphosuccinamate n 30-40% by weight |
