Copper Smelting - an overview | ScienceDirect Topics

Arsenic (as the trioxide) is obtained as a byproduct of primary copper smelting. Flue dusts from copper smelters are collected and As 2 O 3 separated from other smelting byproducts. To obtain gallium arsenide of solar grade, arsenic trioxide must be reduced to metallic form which is then purified by distillation and compounded, at high temperature in a quartz crucible, with purified gallium, obtained …

The EPA regulations in the United States require a primary lead smelter to limit emissions of lead to 3.0 gm per tonne of product. With this emission factor, Copper Cliff would be required to limit emissions of lead to approximately 1 tonne per year, demonstrating that the actual emission is about 150 times greater than allowed by US regulations for a lead smelter.
