GB/T 8152.10-2006 introduces the determination method of silver and gold content in lead concentrates. The lead precipitation or ash blowing gold test is combined with flame atomic absorption spectroscopy (AAS) method. First, the gold and silver in lead concentrates are enriched and separated by fire gold testing to obtain composite particles. Then dissolve the composite particles with suitable reagents, use Flame atomization device to atomize gold and silver, Light spectrum instrument to measure the degree of absorption of specific wavelengths of light, and calculate the gold and silver content according to the standard Linear dispersion. The standard specifies the operation of each link, providing an accurate means for the mass assessment of lead concentrates, and is widely used in lead mining, smelting and related precious metal recycling industries.
