Control of Copper Smelter Fugitive Emissions

With the addi- tion of a silica fluxing agent, the melt forms a copper-bearing matte layer and a waste slag layer. The matte is tapped near the bottom of the furnace, and the lighter slag is tapped at a higher elevation. The slag is collected in a slag pot or ladle, carted to a disposal area, and dumped.
