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: 1 1. Petroleum sulphonate 30-40% by weight 2. Sulphosuccinate 30-40% by weight 3. Sulphosuccinamate 30-40% by weight
Claims12
A process for beneficiation of complex bastnaesite ores containing barite, fluorite, silicates, calcite and iron oxides.
A method of separation of bastnaesite as the main mineral from ores containing barite and fluorite, using reverse flotation of barite and fluorite, followed by flotation of bastnaesite.
The new barite collector that is highly selective against fluorite, calcite, REO, silicates and iron oxides. The new collector, as opposed to a conventional collector, is not sensitive to the presence of ultrafine slimes, and the removal of such slimes before BaSO4 flotation is not required.
