The first step in slag processing is size reduction to liberate metallic iron and iron-bearing 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).

Aside from assessing and evaluating social-environmental concerns and designing the mining and material movement approach, the first question often asked is, "how much will it cost us to mine?" This may need to be determined even before you decide that there is a potential project. Mine cost estimation may be done at many levels.
