Study on Ore Properties and Beneficiation Technology of the Southwest Rare Earth Ore in China AITranslate
Abstract AITranslate
The ore properties of rare earth (RE) ore of Southwest Territory, China, and its beneficiation technology have been studied. The ore is strongly weathered to produce 20% black slime. RE available for commercial use in ore is occurred in two phases: mineral and colloidal. The main (>96%) RE mineral of mineral phase is bastnaesite. The bastnaesite concentrates (30%、 50% and 60% REO) can be obtained by gravity separation or gravity-flotation combined process at 65% recovery of RE. RE minerals of colloidal phase is absorbed in non-crystal minerals of Fe-Mn oxide. It can be recovered by hot HC1 leaching-purification with liquid ammonia-oxalic acid precipitation route at 74.3% of RE, and lead can be obtained as byproduct. The ore and the black weathered minerals are rich in cerium family RE (∑CeO2>90%, CeO2>La2O3>Nd2O3).
