IR Spectroscopy in Determination of Enrichment of Low Quality Bauxites

It is shown that processes of enrichment of low quality bauxite can be as effectively monitored by IR spectroscopy next to other generally applied analytical methods, such as chemicals analysis, X-ray diffraction and atomic absorption spectrophotometry.

description It is shown that processes of enrichment of low quality bauxite can be as effectively monitored by IR spectroscopy next to other generally applied analytical methods, such as chemicals analysis, X-ray diffraction and atomic absorption spectrophotometry. Changes were followed of characteristic vibration bands of main bauxite constituents, boehmite, haematite and kaolinite, as the carries of aluminum (gamma-AlOOH), iron (Fe 2 O 3 ) and silicon [Al 2 SiO 5 (OH) 4 ], respectively.
