Scope
Main technical content: This document describes the method of determining the silver content in silver ore using flame atomic absorption spectrometry in aqua regia medium. This document is suitable for determining the silver content in silver ore samples. The measurement range of Ag (mass fraction): 5.00 g/t to 2500 g/t; the method's detection limit for Ag is 1.25 g/t. Table 1 Precision units: g/t Elemental level range Repeatability limit R Reproducibility limit RAg 18.5 to 1024 r = 0.0155m + 3.1654 R = 0.0239m + 3.1603
