Froth flotation of fluorite: A review - ScienceDirect

2021-4-1  Barite-fluorite separation. Fatty acids can actively interact with Ca and Ba sites on the surfaces of fluorite and barite, causing nonselective adsorption [38,115,169]. Therefore, fluorite and barite exhibit similar floatabilities, and their separation by flotation is difficult [169,170]. Multiple flotation stages are usually required.

Experimental modeling for upgrading of brown barite ore

2018-2-12  Barite powder as a weighting agent is the most important additive into drilling mud for the oil and gas extraction. In this study, production of brown barite powder (SG 4.065 g/cm 3) was examined by flotation (direct and reverse) and magnetic separation for upgrading the quality of fine barite particles and receive it to the standard point for drilling applications (SG higher than 4.2 g/cm 3).

2021-11-20  Barite, also called baryte, is a non-metallic mineral product with barium sulfate (BaSO4) as the main component. The name of barite comes from the Greek word barys, which means heaviness and implies the weight of this mineral. Because the specific gravity of barite is as high as 4.5, which is very rare in non-metallic minerals.
