Micro-flotation experiments confirm that the flotability of bastnaesite is high at pH 6.5–8.5, while calcite floats at pH 8.0–9.5, and barite has little flotation response.

The flotation results show that a barite concentrate assaying 98.21% BaSO 4 can be obtained with the recovery of 80.71%. The agent used in the flotation is water glass as depressant at 500 g/t, sodium oleate as collector at 700 g/t. In the closed circuit, one rougher, three cleanings and one scavenging operations were employed.

Large barite crystals from Nevada. Barite (British spelling Baryte ), also called heavy spar, is a mineral that is widely distributed around the globe. Chemically, it consists of crystals of barium sulfate ( Ba S O 4 ). The pure crystals are white or colorless, but the mineral acquires various colors based on impurities it contains.
