Iron Ore Plant Slag
Comprehensive review on metallurgical recycling and cleaning of copper slag
ResultThe copper slag produced by the slag cleaning furnaces as a final by-product, yields copper in the range of 0.55–1.3 wt.% in the discarded slag, with copper losses of most plants in the discarded slag limited between 0.8 wt.% and 1.0 wt.% (Coursol et al., 2012). However, the final copper slag still contains large …

Mineral Resource of the Month: Iron and Steel Slag
ResultFerrous slag forms as a dominantly calcium silicate melt that floats on top of the molten crude iron or steel; the slag is then removed from the liquid metal. For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about 0.25 to 0.30 metric tons of slag per ton of crude iron produced.
