Kinetics of conversion of celestite to strontium carbonate in solutions containing carbonate, bicarbonate and ammonium ions and dissolved ammonia [PDF]

Journal of the Serbian Chemical Society, 2014
Celestite concentrate (SrSO4) has been converted to SrCO3 in solutions containing CO32-, HCO3- and NH4+ ions and dissolved ammonia. The effects of stirring speed, CO32- ion concentration; temperature and particle size of SrSO4 on the reaction ...

Preparation of strontium hexaferrite magnets from celestite and blue dust by mechanochemical route [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2008
In the present investigation celestite (natural ore of strontium) and blue dust (iron ore fines) have been used for the preparation of strontium hexaferrite powder. The mechanical alloying process has been adopted to prepare strontium hexaferrite powder.

Strontium-induced genomic responses of Cupriavidus metallidurans and strontium bioprecipitation as strontium carbonate

Annals of Microbiology, 2012
The physiological and global transcriptomic response of the metal-resistant bacterium Cupriavidus metallidurans CH34 to stable non-radioactive strontium (Sr) was investigated. C. metallidurans CH34 was able to survive and proliferate in the presence of relatively high concentrations of SrCl2 (concentration of Sr needed to inactivate 90 % of the cells =

Effect of carbonate chemistry alteration on the early embryonic development of the pacific pyster (Crassostrea gigas) [PDF]

, 2011
Ocean acidification, due to anthropogenic CO(2) absorption by the ocean, may have profound impacts on marine biota. Calcareous organisms are expected to be particularly sensitive due to the decreasing availability of carbonate ions driven by decreasing ...

Authigenic Clays Versus Carbonate Formation as Products of Marine Silicate Weathering in the Input Sequence to the Sumatra Subduction Zone

Geochemistry, Geophysics, Geosystems, 2022
We use geochemical and petrographic data from anoxic sequences of the Nicobar Fan to document extensive marine silicate weathering (MSiW) in the input sediment of the Sumatra subduction zone and the conditions that result in authigenic minerals ...
