Non-ferrous slag recycling plant coming to Romania Non-Ferrous Metals – Kirstin Linnenkoper – June 8, 2018 Greek holding Mytilineos has announced that it will invest EUR 33.8 million (US$40 million) to build a slag processing and recycling plant in Romania, where it owns a lead and zinc smelter.
Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further …
Recycling:Following removal of entrained metal, slag can be returned to the blast and steel furnaces as ferrous and flux feed, but data on these returns are incomplete.
### __FUN FACTS__ Ferrous slags have been produced and used since the dawn of the Iron Age. Slag use is one of the great and relatively unsung stories of material reuse and recycling. Slags are coproducts of iron- and steelmaking; they are not waste products.
