This paper studies the influence of two pH modifiers, namely sodium hydroxide (NaOH) and sodium carbonate (Na2C03), on the flotation of celestite ore using sodium oleate as the collector and sodium silicate (Na2SiO 3) as the depressant. The use of Na2CO 3 provides the best results for the concentration of celestite, under the same experimental conditions. © 1998 Elsevier Science Ltd. All rights...

the qom formation, which hosts the mazraeh celestite deposit, contains dominantly limestones, marl and subordinate evaporites deposited in shallow marine environments. petrographic evidence indicates that the celestite deposits were formed by replacement of limestone. the presence of carbonate inclusions within celestite crystals as well as the pseudomorphic habits of some crystals suggests tha...

Detailed petrographic, geochemical and strontium isotope studies, combined with field observation and rnicrofacies investigations indicate that syngenetic celestite at the base of Asmari Formation at the Bangestan anticline, Behbahan region, was deposited directly from Tertiary seawater in an intrasupratidal to supratidal environment. During diagenesis, the precipitated celestite underwent ...

Strontium carbonate (SrCO3) is one of the most important strontium compounds that have been used in a variety of technological and industrial applications. In the present investigation, nano-structured strontium carbonate was synthesized by mechano-chemical reaction of celestite ore (SrSO4) collected from Dasht-e kavir, Iran and sodium carbonate during high energy mechanical milling.The milling...
