Abstract：Bauxite has strong chemical stability and belongs to a kind of ores which are hardly composed. It brings some difficulties to its analysis and determination.The progress in digestion methods and analytical techniques of bauxite sample in recent ten years was mainly reviewed. The sample digestion methods included acid digestion in open system, microwave digestion, high-pressure digestion, alkali fusion, NH4F and NH4HF2 digestion. The analytical techniques included inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), X-ray fluorescence spectrometry (XRF) and laser induced breakdown spectroscopy (LIBS). In addition, the development of sample digestion methods and analytical techniques for bauxite samples were prospected. Total 66 references were cited.
