Scope

This part of YS/T 1050 specifies the determination methods for the gold and silver content in lead-antimony concentrates.
This part is applicable to the determination of the gold and silver content in lead-antimony concentrates, with a determination range (mass fraction) of 0.50 g/t to 25.0 g/t for gold and 100 g/t to 3,000 g/t for silver.
When conducting arbitration analysis, if the silver mass fraction is ≤500 g/t, the flame atomic absorption spectrometry (YS/T 1050.9—2015) shall be used.
