TACOMA SMELTER PLUME SITE CREDIBLE EVIDENCE …

ASARCO's primary copper smelter in Ruston, Washington operated for almost 100 years. Final copper smelting occurred in 1985, with some processing of high-arsenic materials continuing into 1986. While the Tacoma Smelter was still operating, it was included as part of the Commencement Bay Superfund Site.

Smelting Furnace

The advantages of flash smelting over roasting/electric furnace melting are that flash smelting: (1) requires much less energy than electric smelting and (2) avoids the electric furnace's emission of weak SO 2 gas [31]. It is also a high production rate process, perfectly matched to the 50–100-μm particles in froth flotation concentrates.
