About 20% of slag is dumped into the slag cooling pit and crushed with mechanical crushing systems after cooling. The crushed slag is passed through magnetic separators to separate the metal. The metals are collected as recycled metal and the remaining slag is an iron free material suitable for cement plant admixture with maximum size of 4.5mm.
