Steel slag from an electric arc furnace (EAF) may contain significant amounts of oxides of valuable metals. The recovery of iron and other metals from the EAF slag using smelt-reduction process was studied with coal as the reductant. A pig iron phase with high carbon and a final slag depleted of the valuable metals were generated.
Read MoreWaste to wealth. 1. Introduction. Today steel slag (SS) is one of the most discussed solid wastes in the world apart from blast furnace (BF) slag, fly ash, and municipal solid wastes. The former two are byproducts from iron and steel production; an activity indispensable for the structural growth of any nation.

Steel slag is a major by-product generated by the steel industry. Although steel slags are classified as non-hazardous thermal waste according to the decree 2002–540 and US EPA [], it is well known that most metals they contain are quite toxic to living organisms and may pose serious environmental issues.In France, the CTPL []

1. Introduction. In 2016, the global steel production was 1360 million tonnes (WSA, 2017), generating around 170 to 250 million tonnes of steel slag as a major by-product (Gomes et al., 2016b; USGS, 2017a).Recycling of this slag as construction materials has long been a research focus and an established afteruse, with up to 70% of
