Fusion Extraction of Base Metals (Al, Cr, Fe, Ti and V) Using Ammonium Phosphate Salt as Flux

The fusion method of using ammonium phosphate salt as flux was assessed for its ability to precipitate metaphosphate compounds containing trivalent ions M3+ = Al, Cr, Fe, Ti, and V M(PO3)3 in inorganic salts a certified reference material (CRM) mineral ore sample. Fusion analysis mixtures AlCl3, CrCl3, FeCl3, VCl3 showed variable amounts precipitates isolated the order iron (12%) < vanadium (13%) chromium (30%) (44%) aluminum. However, an CRM (AMIS 0368) where magnetite (Fe3+/Fe2+) ilmenite (Ti4+) are dominant phases, that obtained were (less than 0.1%) (1%) aluminum (2%) titanium (9%) (68%). via use this identified XRD analysis. SEM–EDX micro-crystalline particles from irregular clustered, contrary amorphous micro which produced CRM. degree specificity improved considerably with high content (~76%, Fe3+/Fe2+). This shown be highly selective towards metals stable oxidation state. No other elements different state precipitated.
