摘要: Synopsis Qualitative analysis of three mineral samples from northern Mozambique was accomplished by X-ray diffraction (XRD), microscopy, scintillation, and magnetic determination. Chemical characterization using ICP-OES pressed powder XRF after dissolution microwave-assisted digestion flux fusion. The consisted a mixture minerals with tantalite as the major component, minor amounts microlite, quartz, mica, accessory garnet, tourmaline. Incomplete obtained microwave digestion, maximum recoveries 90.25 ± 0.06% 88.90 0.04% for Nb 2O5 Ta2O5 respectively. Complete Li 2B4O7 resulted in 98.5 0.2% Nb2O5 100.4 0.3% Ta2O5.
