Selective flotation of fluorite from barite using trisodium phosphate as a depressant
Minerals Engineering, 2019In this paper, trisodium phosphate (TSP) was utilized for the flotation separation of fluorite from barite. Micro-flotation results showed that good floatability of both fluorite and barite was obtained at around pH 8.5 using sodium oleate (NaOL) as a ...

Abstract Incidences with sag of solid weighting agents in drilling fluids can lead to potential drilling impediments including; loss of wellbore control, lost circulation, stuck pipe and high torque. The presence of sag has relatively often been the cause for gas kicks and oil-based drilling fluids are known to be more vulnerable for sag

Natural radioactivity of barite concrete shields containing commonly used supplementary materials
, 2020The recycling of hazardous materials within new composites has a sustainable importance as it contributes on the reduction of high radionuclide concentrations. In this study, the effect of cementitious materials i.e.

Abstract Authigenic barite has been identified in soil pedons in southeastern Oklahoma, eastern Texas, and northern Louisiana. The barite appears as fine, white powder on structural surfaces and in small pockets in the lower argillic horizon or just beneath it.

Abstract Theoretical calculations of barium sulphate saturation in the sea water column have been compared to the barium concentrations in the eastern Pacific Ocean and in pore waters filtered from sediments containing marine barite. There is good agreement between the calculated saturation value, 44–49 μg/kg barium at 4–5 km depth and 1°C, and the ...
