Ferrous Slag – general information - Euroslag

2021-9-28  Iron and steelmaking slags (ferrous slags) are co-products of the iron and steel making industry. They are non-metallic rock-like materials which are produced together with the metallic products of these processes. Depending on the iron and steel production process different slag types can be manufactured. Blast furnace slag is made during the melting and reduction of iron []

Slag recycling - recovery

In 2018, the country produced 27.271 Mta of pig iron and a total of 42.435 Mta of crude steel. This corresponds to 30 % of the total pig iron production and 25.3 % of crude steel production in the EU28. As a result, Germany produced 13.18 Mta of iron and steel slag, of which 7.79 Mta were blast furnace slags and 5.39 Mta were steelworks slags.
