secondary copper smelters

BACKGROUND REPORT SECONDARY COPPER SMELTING,

2021-6-25  Secondary copper recovery is divided into four separate operations: scrap pretreatment,smelting, alloying, and casting. Pretreatment includes the cleaning and consolidation of scrap inpreparation for smelting. Smelting consists of heating and treating the scrap for separation andpurification of specific metals. Alloying involves the addition of one or more other metals to copperto obtain desirable qualities characteristic of the combination of metals. The major secondarycopper smelting

AP-42, CH 12.9: Secondary Copper Smelting

2015-9-10  Fugitive emissions occur from each process associated with secondary copper smelteroperations. These emissions occur during the pretreating of scrap, the charging of scrap into furnacescontaining molten metals, the transfer of molten copper from one operation to another, and frommaterial handling. When charging scrap into furnaces, fugitive emissions often occur when the scrapis not sufficiently compact to allow a full

Control of Copper Smelter Fugitive Emissions

Secondary emissions still must be controlled around the other process furnaces. Use of this system at copper smelters might permit the use of fewer converters and could yield a stronger S02 stream, but would require holding furnaces for good process control.
