What the source says
Primary copper smelting is the industry which refines copper sulfide ore concentrate from mined ore to produce anode grade copper, using pyrometallurgical processes. Pyrometallurgical processes use high temperature furnaces to smelt or refine ores to produce pure metals or metal oxides. The final rule for area sources will ensure emissions of air toxics are minimized and improve compliance assurance.
