Flotation separation of barite from calcite using

Oct 20, 2019· The above results suggest that flotation separation of barite from calcite can be realized when the AWG is used as a depressant for calcite. Hence, flotation tests of barite and calcite mixture with the mass ratio of 4:1 were performed in the present and absence of AWG using NaOl as the collector at pH ˜8, the result of which is shown in Table 2.

Barite (BARIUM)

Barite (BARIUM) Introduction Barite is a mineral composed of barium sulfate, BaSO 4. It is usually colorless or milky white, but can be almost any color, depending on the impurities trapped in the crystals during their formation. Barite is relatively soft, measuring 3-3.5 on Moh’s scale of hardness. It is unusually heavy for a non-metallic
