Infrared was used to monitor the progression of barite (BaSO4) and gypsum (CaSO4·2H2O) crystallization. It was found that barite crystallized with broad infrared peaks that narrowed over time. This was accentuated when an inhibitor was added. The infrared of gypsum in the early stages showed a phase that was

Secondary ion mass spectrometry was used to test the δ 18 O and δ 34 S nanogram-scale homogeneity of a suite of candidate sulfate minerals, ultimately selecting three barite, two anhydrite, and two gypsum samples from the Royal Ontario Museum that have repeatabilities for their SIMS measurements of better than ±0.39‰ and ±0.37‰ (1s) for …
By Mark Leatherman. Barite has got to be one of my favorite minerals to collect for a variety of reasons: 1) its unique heft for being a nonmetallic mineral, 2) the variety of colors and conditions it can form under, 3) its flat, tabular crystal forms, and 4) its practical usage in products ranging from paper, paints, plastics, and petroleum drilling to medicine, vehicle engines, and …
To this end, real AMD was used to synthesize goethite, hematite, magnetite, and gypsum (product minerals). Drinking water was also reclaimed as part of the treatment process, hence rendering this system a zero-liquid-discharge (ZLD) process. For the synthesis of goethite, hematite, and magnetite, Fe(III) and Fe(II) were recovered via sequential ...

Mineral solubility predictions are critical for estimating scaling risks at conditions of high temperature, pressure, and ionic strength (IS) in mixed electrolytes which occur in various industrial processes. On the basis of the Pitzer theory, this study establishes a thermodynamic model to predict the solubilities and scaling risks of barite, calcite, gypsum, and anhydrite …
The Wengeqi mafic–ultramafic intrusion is located in the northern margin of the North China Craton (NCC), which was an Andean-style active margin in the Paleozoic (Meng and Ge, 2001).The intrusion contains many platinum-group minerals (PGMs) (Su and Lesher, 2012; Liu et al., 2013), and is one of several PGM-bearing mafic–ultramafic intrusions along the northern …
