The principle of the slag wet treatment process is re-election, because the density of non-metallic substances such as slag, glass, ceramics, etc. in the slag is 1.2 to 2.7 g/c. Between m3, the density of metals such as iron, copper and zinc is 7 to 9 g/cm3, and there is a large difference in specific gravity between the two types of substances.

Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.

The burden starts to soften. Iron and slag separate. The FeO content in slag phase can vary inside a large range, e.g., 5–25%. Metallic iron is carbonized by carbon in the coke and CO gas and melts at 1200–1300 °C. Molten iron and slag drip down through the coke layer to the hearth where they reach their final temperature and composition.
