Gold Recovery : 8 Steps (with Pictures) Instructables

Cupellation is a process 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 led, copper, zinc, and others present in the ore or alloyed metal. The process is based on the principle that precious metals do not oxidize or react chemically, like the base metals; so when they are heated at
