BACKGROUND REPORT PRIMARY COPPER SMELTING

called electrowinning. SX-EW capacity in the U.S. was 358,000 megagrams (395,000 tons) in 1989. The SX-EW process is an alternative to smelting, but it and its emission streams are fundamentally different from smelting, and as such it will not be addressed in detail in this document.

Production of Gold

The smelting step of refining consists of heating the loaded steel wool to melt the gold at 1300°C, with fluxes of silica, feldspar, and borax, to remove impurities. Complete separation occurs within 1.5 hours, at which point the slag is poured off and the molten gold is poured into anode casts and cooled. The anodes are approximately 99%
