During a three-year period, the Company, operating as a Mexican Subsidiary named USAMSA, mined antimony at Sierra Guadalupe in Zacetecas, Mexico and smelted at …
The alkaline leaching process of antimony from different minerals has been studied by many researchers (Anderson et al., 2012; Awe and Sandström, 2010, Guo et al., 2019, Han et al., 2020). The kinetic study revealed that the alkaline leaching process of pyroxene is mainly influenced by the contraction nucleation model (Pavel et al., 2012 ...
The antimony ore beneficiation methods mainly include manual separation, gravity separation, flotation, and other methods. Select the beneficiation process of a specific ore based on the physical and chemical properties of the ore type (natural type and industrial type), mineral composition, structural structure, and process particle size of useful …
In the hydrothermal process, the precursor reactants play an important role in controlling the film formation process and thus the film quality. In this study, Sb 2 O 3 is applied as a new Sb source to replace the traditional antimony potassium tartrate to modulate the growth process of the Sb 2 S 3 film.
