The effect of depressant citric acid (CA) on flotation separation of celestite from fluorite and calcite using anionic collector sodium dodecyl sulfate (SDS) is investigated. Through a series of micro-flotation tests, solution chemistry and reaction thermodynamic analysis, zeta potential measure...detailed
The major celestite deposits in Zagros Fold belt are associated with coastal marine carbonate and evaporate sediments of Oligo-Miocene Asmari and Lower Miocene Ghachsaran Formations. In the Abolfares region, celestite mineralization is extended in the western limb of Bangestan anticline in the c...detailed
From viewpoints of long-term safety assessments of disposal systems, it has become an important issue to clarify effects of porosity in compacted illite on diffusion behavior of non-sorbed species, cations, and anions. Therefore, in this study, celestite precipitation was artificially induced in...detailed
Celestite (SrSO4) single crystals immersed in highly concentrated Na2CO3 aqueous solutions (0.5 mol/l) are progressively pseudomorphised by aggregates of strontianite (SrCO3) crystals at ambient conditions. This replacement occurs by the coupling of dissolution and crystallisation reactions, eve...detailed
Atmospheric NO is one of the toxic and hazardous gases. Its’ levels are continually rising in recent years. As we known, mineral particles contained in the atmosphere may affect the photocatalytic NO removal process. In this study, we found that celestite modification could greatly improve the ...detailed
The dissolved components of calcium-bearing gangue minerals will adsorb onto the celestite surface, which increases the difficulty of the flotation separation of celestite from fluorite and calcite. Single mineral and artificial mineral flotation experiments show that EDTA exhibits an excellent ...detailed
