The rapid depletion of high-grade rare earth elements (REE) resources implies that future supplies may be augmented with low-grade ores, tailings, and other unconventional to meet cut-off grades and, subsequently, supply demands. This paper presents an amalgamation studies conducted on selected complex iron-oxide-silicate-rich the overall aim developing efficacious methods associated process mi...
