Chapter 8 Environmental Aspects Of Copper Production

In making sulfuric acid, the hot gases are first collected from the roasters, furnaces, and con-verters see box 8-B. The gases are cooled, cleaned through three series of dust collection systems to recover copper from the dust and prevent foul-ing of the acid plant, and then treated with sul-furic acid to remove any water vapor.

Gold and silver are products of the copper mining and smelting process. They follow the same production pathway as our copper ore from the mine to the smelter. At the refinery, we lower copper anodes which contain gold and silver into an acid solution. Gold and silver drop off into the bottom of the tank as electrolytic slimes.
