In 1974, the 1,000-foot double-shell concrete stack was built by ASARCO to discharge exhaust gases from the smelting operations, which replaced the 300-foot reverberatory furnace stack and 250-foot converter stack. In 1982, construction of Tailings Impoundment D began with an 8,700 feet long and 48 feet high starter dike.

12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)

On this cloudy July morning, inside the former Asarco copper smelter, Walter Boyle, the on-site manager, drives an old pickup truck along a road strewn with piles of twisted metal.

Flash furnace smelting consists of blowing fine, dried copper sulfide concentrates and silica flux with air, oxygen-enriched air, or oxygen blast into a hearth-type furnace maintained at approximately 1200 E C (2200 E F).

Converter Retrofit Project. Landmark EPA legislation created new SO2 NAAQS with ambient air concentration limit of 75 ppb SO2. GCT developed the project for Asarco Hayden Smelter from concept through to implementation, commissioning and start-up to significantly reduce SO2 and dust emissions from the smelter.

The Oxygen Flash Furnace At the Asarco copper smelter in Hayden, Arizona, the oxygen flash furnace is initially heated up with natural gas. It becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silica-bearing flux.

In 1974, the 1,000-foot double-shell concrete stack was built by ASARCO to discharge exhaust gases from the smelting operations, which replaced the 300-foot reverberatory furnace stack and 250-foot converter stack.
