12.1.2 Hearth furnace refining (Alarcon, 2005). Although the rotary furnace dominates copper fire refining in primary smelters, secondary (scrap) smelters tend to use hearth-refining furnaces (Hanusch, 2010; Rinnhofer & Zulehner, 2005).They are better for melting scrap and other solid inputs. Sulfur is removed by reaction of the copper solids with an oxidizing flame above the …
