Characteristics and environmental aspects of slag: A review

Slag examined in this study is defined as the predominantly silicate and oxide by-product derived from smelting metallic ore. The two main types of slag included in this discussion are from the primary production of ferrous ores, from iron and steel manufacturing, and from non-ferrous ores, from the recovery of base metals and some precious metals.
