Warning. Personnel using this standard should have hands-on experience in formal laboratory work. This standard does not address all possible security issues.
It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the relevant national laws and regulations.
1 Scope
This standard specifies the method for identifying bauxite by X-ray diffraction.
This standard applies to the qualitative identification of bauxite.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Bauxite bauxite
Aluminium with a high aluminum content (more than 40% Al2O3 content) and an ore with Al/Si ≥ 2.5. If it is less than this value, it is called clay or aluminous rock or
Aluminous shale.
4 Principle of the method
The sample is crushed and sieved to prepare an analytical sample. The phase structure analysis of the sample is carried out by X-ray diffraction.
From the characteristic diffraction peaks, according to the comparison between the three strong peaks in the spectrum and the standard map, the type of hydrated alumina contained in the sample is judged.
The physical form, alumina content, and aluminum to silicon ratio were determined to determine the type of sample.
5 reagents and materials
5.1 Standard materials for bauxite ore. National certified standard substances.
5.2 Slides.
5.3 Sample box.
5.4 Standard Alumina Sheet. For zero calibration.
