Grinding Mill an overview ScienceDirect Topics
The first step in slag processing is size reduction to liberate metallic iron and ironbearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003).
