Cupellation Wikipedia
Cupellation is a refining process in metallurgy in which ores or alloyed metals are treated under very high temperatures and subjected to 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 [1] [2] [3] The process is based on theFor example, the primary process of zinc metal production through smelting requires approximately 375 GJ/t Zn and emits approximately 266 t CO 2 eq/t Zn (van Genderen et al 2016)Flowchart of zinc concentrate production ResearchGate
