Beyond the silicate matrix: SQUID magnetometry and Raman spectroscopy reveal hidden hausmannite in sintered manganese ores

The depletion of high-grade manganese reserves necessitates the effective beneficiation of low-grade ferruginous manganese resources, which constitute the dominant share of Kazakhstan’s reserve base. This study investigates the structural and magnetic evolution of carbonate-rich Bogach and silicate-...
