3 Method summary
3.1 Lead chromatography
Sample by fire assay melt, slag, lead generation quality deduction is reduced to 2g ~ 5g.
First of slag slag and slag generated in the process of re-processed to produce low levels of lead and silver buckle, reduced through the slag, lead quality buckle
2g ~ 5g.
The resulting lead button twice dissolved in nitric acid, the solution is filtered. Dissolving paper and gold, gold and silver content was measured by flame atomic absorption spectrometry.
3.2 cupellation
Sample by fire assay melt blown gray, gold and silver together to give tablets.
First of slag and soot blowing ash pan re-processing of gold and silver together to get another grain.
Gold and silver together two tablets dissolved in nitric acid, the solution was filtered. Dissolving paper and gold, gold and silver content was measured by flame atomic absorption spectrometry.
