GB/T 3257.24-1999 Methods for chemical analysis of bauxite--Determination of hydroscopic moisture in analytical samples--Gravimetric method (English Version)
This standard specifies the method for the determination of wet water content in bauxite ore analysis samples. This standard is applicable to the determination of wet water content in bauxite ore analysis samples, and the measurement range is 0.1% to 5.0% (expressed as H2O). At the same time, it is also used to correct the measurement results of the loss on ignition at 1075°C to the dry basis value. Note: When moisture needs to be considered for other determinations, the pre-dried samples should be prepared in accordance with the provisions of GB/T3257.22.
