摘要:

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 (Fe2O3) and silicon [Al2SiO5(OH)4], respectively.
