A new database was developed to successfully model the solid and aqueous phase equilibria in a number of hydrometallurgical processes using the Mixed Solvent Electrolyte (MSE) model of the OLI Systems software. In order to validate the predictability of the model developed, a number of experimental measurements were conducted in multicomponent solutions containing NiSO4, H2SO4, MnSO4, HCl, etc....

Due to a mistake during the production process, fourth author’s name was incorrectly published as ‘Yang I. Huh’ instead of Il Huh’. The should be tagged in XML given Il’ and family ‘Huh’. cited indexing services ‘Huh Y’.

Phosphogypsum is a waste produced by the phosphate fertilizer industry. Although phosphogypsum is mainly calcium sulphate dihydrate, it contains elevated levels of impurities, which originate from the source phosphate rock used in the phosphoric acid production. Among these impurities, radionuclides from 238U and 232Th decay series are of most concern due to their radiotoxicity. Other elements,...

Single-distilled water encapsulated in graphene pockets has been studied by aberration-corrected high-resolution transmission electron microscopy and electron energy loss spectroscopy at an acceleration voltage of 80 kV. Inside the graphene pockets, crystallization and in situ crystal growth are reported and identified as the insoluble AII phase of CaSO4 (anhydrite) in a quasi-two-dimensional s...

Scale formation and well plugging due to the incompatibility of injected waters is a critical field problem in oil recovery. A water injection process was successfully performed when the identification of the source of water, water quality considerations, and laboratory compatibility tests were considered. When different waters are mixed, it is necessary to evaluate their compatibility prior to...

The gas sulfur reduction of phosphogypsum in the acid co-production sulfoaluminate cement clinker is a new process for treating phosphogypsum. furnace this system was studied and analyzed by combining computational fluid dynamics (CFD) experimental validation. effects n(CaSO4)/n(S2), particle residence time, kiln tail flue temperature on performance were obtained. A second-order response model ...
