· 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 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 appliions (SG higher than g/cm 3).
The results also indie that a pronounced selectivity effect was obtained from the ultrasonic flotation of both barite and chalcopyrite. The use of ultrasound in the froth remarkably improves the quality of the chalcopyrite concentrate, especially at the shallow froths.
· When the concentration of AWG increased to 180 mg/L, the BaSO 4 grade of flotation concentrate improved to % with % recovery. The flotation of mixed minerals confirmed that AWG depressant can be used for the flotation separation of barite and calcite when using NaOl as .
· From the comparison of their photos, the flotation concentrate was obviously darker than the raw BS sample due to the high carbon content. Since the flotation concentrate was mainly carbon, it can be recycled as raw material in the carbothermal reaction process of barite. 4. Conclusions

The flotation of barite minerals were carried out in an alkaline condition at pH 9 with sodium oleate collector and terpineol frother. It was found that concentrate grades of barite for the air flow rates of 20, 30 and 40 L/min were nearly constant about 70% BaSO4 at the immersion depths of 5 and 10 cm but it increased at the depth of 15 cm.
· Digesting of a flotation concentrate with sulfuric acid converts the rareearth compounds firm fluorcarbonates to sulfates. Action of the acid releases gaseous compounds of fiuorine and silicon, leaving the sulfated material free of these elements; carbon dioxide from carbonate decomposition is eliminated at the same time.
· Taking the separation of barite quartz calcite ore as an example, in the combined flotation gravity separation process, sodium silie and collector are added to the flotation cell to remove quartz to obtain the mixed ore of barite and calcite, which are separated by a jig and a shaking table due to density difference between calcite and barite to obtain barite concentrate.
The flotation rate curves show that recovery of barite is increased and there is less random behavior with higher flow rates of nitrogen. For the coarser sized barite, the recovery vs. collector concentration curves are very steep reflecting the formations of hemimicelles.
The flotation of bastnaesite, as a major mineral source of rare earth elements, attracting much attention in the mineral processing field, is challenging owing to the natural flotability of calciumbearing minerals. To promote the appliion of flotation, we systematically investigated the flotation behavior of bastnaesite, barite, and calcite, with salicylhydroxamic acid (SHA) as the ...

However, the floatation separation will get better baryte powder while gravity separation can help to get lumpy barite concentrate like 250mm. 1. Flotation separation This method works based on the chemical and physical property difference between barite surface and associated minerals surface; The main equipment includes crusher, circle ...
The results from barite flotation using lauryl phosphate as a collector is shown in Figure 4. It is obvious that the barite flotation recovery increases as a function of lauryl phosphate concentration at different pH. Furthermore, all the barite recovery reaches 95% at 1 × 10 −5 M lauryl phosphate concentration for pH, pH, and pH
· Microflotation results revealed that OBHA exhibited superior collecting ability to bastnaesite but did not float calcite and barite. A bastnaesite concentrate with around % REO grade and about % recovery can be obtained from the bastnaesite and calcite mixed mineral, for bastnaesitebarite mixed system, nearly % bastnaesite was ...
