Flotation of Rare Earths from Bastnasite Ore
Scavenger flotation tests on the cleaner tailing were made to prepare a marketable rare-earth product and to minimize the rare-earth loss. Since approximately 10 pct of the tailing was plus 150 mesh and electron microprobe analysis indicated locked bastnasite grains, regrinding of the cleaner tailing to minus 150 mesh would be advantageous.
