The solvent extraction separation of molybdenum and copper from acid leach residual solution of Chilean molybdenite concentrate
(1995)
A procedure for recovery and separation of molybdenum (VI) and copper (II) from acid leaching residual solution of Chilean molybdenite concentrate by solvent extraction is studied. The process for the recovery of metals ...
Captura de dióxido de carbono (CO2) em processos de carbonatação mineral
(Universidade Estadual Paulista (Unesp), 2021-12-02)
A tecnologia de carbonatação mineral mostra-se como um processo promissor para reduzir as emissões de CO2 na atmosfera. Entretanto, apresenta um alto custo de operação devido ao consumo de elevadas quantidades de energia ...
Nutritional and mineral contents of honey extracted by centrifugation and pressed processes
(2017-03-01)
In this study, wild honey samples extracted by two different methods (centrifugation and pressed processing) were characterized and compared based on their physicochemical, and nutritional properties, macro- and micro-mineral ...
Leaching optimization of mining wastes with lizardite and brucite contents for use in indirect mineral carbonation through the pH swing method
(2017-01-10)
This study investigated the leaching process in order to maximize Mg and Fe extraction and to produce amorphous silica (SiO2) with high purity. For this, a mining waste identified as S-GO was employed; which is a serpentinite ...
The Role of Solar Energy (UV-VIS-NIR) as an Assistant for Sulfide Minerals Leaching and Its Potential Application for Metal Extraction
(MDPI, 2021)
The mining industry is facing emerging challenges as a result of the increase in energy
consumption and environmental demands. These facts have promoted the use of renewable energy
sources, such as wind, geothermal and, ...
