Sr/Ba in barite: a proxy of barite preservation in marine sediments?
Marine Geology, 2003 Abstract The observation by Bertram and Cowen [J. Mar. Res. 55 (1997) 577–593] that the strontium content of marine barite decreased from the water column to the deep-sea floor suggested that the Sr/Ba ratio in barite was sensitive to barite dissolution. Following this observation, we have investigated the potential of using the Sr/Ba ratio in barite

Kinetics of barite reduction from refractory barite-sulphide ore
Metallurgical and Materials Engineering, 2016 Refractory sulphide–barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships of lead, copper and zinc minerals with gangue minerals, it is not possible to enrich the ore using the conventional methods of ...

The Formation of Barite and Celestite through the Replacement of Gypsum
Minerals, 2020 Barite (BaSO4) and celestite (SrSO4) are the end-members of a nearly ideal solid solution. Most of the exploitable deposits of celestite occur associated with evaporitic sediments which consist of gypsum (CaSO4·2H2O) or anhydrite (CaSO4). Barite, despite
