Cupellation - Wikipedia

Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have 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. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the ...

CHAPTER 5. POTENTIAL FOR HUMAN EXPOSURE

Antimony is also produced as a byproduct of smelting primary lead ores. Primary smelter outputs were 19,675 metric tons in 1992. Almost as much antimony is produced from scrap as from ore. Antimony produced from secondary sources is primarily derived from "old scrap," generally consisting of lead battery plates, type metal, and bearing metal.
