The electrolytic production of metallic zinc from processing zinc sulfide concentrates generates a residue containing cadmium, copper, and cobalt that need to be removed from the electrolytic zinc solution because they are harmful to the zinc electro-winning process. This residue is commonly sent to other parties that partly recover the contained e...

A full factorial experimental design was conducted to investigate the effect of temperature and depressants on the flotation of monazite and bastnaesite from carbonate gangue minerals. Temperature, sodium silicate, and guar gum dosage were examined. Mineral reconstruction from energy-dispersive x-ray fluorescence (EDXRF) data was performed to quant...

... Meanwhile, the production and development of cobalt ion recovery methods has received much attention (Junior et al., 2021). Knowledge of cobalt extraction technology depends on the type of application resources Boisvert et al., 2020;Huang et al., 2021). Crundwell and co-workers illustrated the applied processes for the prediction of cobalt from copper-cobalt ores in the African Copperbelt region (Crundwell et al., 2020). ...
... Monazite is the second largest source (accounting for 13% overall) of REEs after bastnaesite (83%) (Boulanger et al. 2019). Monazites are found in igneous and metamorphic rocks, and as complex ores associated with iron oxides, aluminosilicates, and apatite (Ferron et al. 1991;Chang et al. 1998;Wall 2014). ...
