What is a Copper Slag? with pictures - wiseGEEK

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of appli ions in the building and industrial fields.

Copper extraction - Wikipedia

Slag is less dense than matte, so it forms a layer that floats on top of the matte. Copper can be lost from the matte in three ways: as cuprous oxide Cu 2 O dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets or prills of matte suspended in the slag.
