This metal needs no introduction. Silver has been known since ancient times, but its usage is more recent than that of gold. The cupellation process, which is the refining process in metallurgy when ores or alloyed metals are treated at very high temperatures to separate noble metals such as gold and silver from base metals such as lead and copper, is believed to have been developed in the 6th ...

Gold-Silver Separation. The initial step is to weight the Dore metal. Since silver is leached by nitric acid and gold no, the next step is to attack the Dore metal with a hot diluted solution of nitric acid. The acid dissolves the silver and leaves the gold that has to be rinsed, dry, and weight on a scale of high sensibility such as 0.001 mg.
