Does it really even break down the gold too ?
*Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore.
Actually HCl + H2O2 will dissolve gold. The peroxide acts as an oxidiser (HCl is a nonoxidising acid) and the free chlorine will dissolve some gold into solution. The presence of copper which is higher in the reactive series of metals will subsequently drop the gold as a fine dust.
