GB/T 1819.13-2004 Methods for chemical analysis of tin concentrates Determination of magnesium oxide and calcium oxide contents-Flame atomic absorption spectrometric method (English Version)
This standard specifies the determination method of magnesium oxide content and calcium oxide content in tin concentrate. This standard applies to the determination of magnesium oxide content and calcium oxide content in tin concentrate. Measuring range: magnesium oxide 0.010% ~ 2.00%; calcium oxide 0.050% ~ 7.00%.
