Metallic slags are produced from the by-products of the refining process. Similar to coal slag, the molten slag is rapidly cooled and the resulting material is crushed and screened. While metallic slags are slightly harder than coal slag, their performance and inherent issues are basically the same. Metallic slags are primarily used in the geographic regions where their base metals are refined.
