As an effort to make progress from economical and ecological perspectives, the ironmaking field is expanding the recycling of ferrous by-products. Copper slag has been widely recycled in the abrasive media, the pavement, and the cement industries. However, there was no successful activity of recycling copper slag in the steel industry.

Alfametal is one of the leading industrial ferrous and non-ferrous metal recyclers in Spain. Present all around the country, their plants are specialised by metal type and production process. Through ...
Ferrous scrap metals: These are the most common types in recycling yards. They contain iron and, as a result, are magnetic. Examples include mild steel, carbon steel, wrought, and cast iron. Non-ferrous scrap metals: These are more malleable than their ferrous counterparts and are non-magnetic because they don't contain iron. …
The ferrous slag is able to be recycled in internal recycling (reutilization in steel plants), civil construction, agriculture, etc. Internal recycling of slag after magnetic separation in iron- and steelmaking industry is attempted in multiple ways.
Slag is a by-product that results from the metallurgical process of steel or non-ferrous metal production. The main components of slag are oxides of silicon, aluminum, calcium and magnesium, as well as some other elements in smaller quantities that may be present in the ore or added during processing.
Steelmaking plants continuously strive to reduce the environmental load in the steelmaking process, resulting in the recycling of energy, water, and other byproducts. In this chapter, techniques for the treatment and recycling of metallurgical slags are described. Metallurgical slags are considered secondary raw materials and are used or …
SMS group is taking the path to base future solutions in the non-ferrous metals sector on the circular economy (CE). Therefore, the recycling of valuable metals is one of the key enablers for the CE.
A search for the types of ferrous slag [e.g., iron slag, steel slag, basic oxygen furnace (BOF) slag, electric arc furnace slag, BF slag, ladle slag] in the titles of abstracts and citations in the Scopus database 23 gives a query result of over 5000 documents for 2010 to 2020. A small fraction (around one in ten) of those documents …
However, the non-ferrous slag varies in composition resulting in different chemical properties for AAMs and OPC, and the effect of S/S on HMs. The selection and the chemical interactions of the solid wastes are important for the formulation of the cementitious system. ... Effective disposal of hazardous waste from non-ferrous waste …
Non-ferrous metallurgy slags, e.g. copper slags, for example, are often merely used for sandblasting or as road base filler (Dhir et al., 2016; Murari et al., 2014; Piatak et al., 2015). In the Belgian region of Flanders, 376 kt of non-ferrous slag is produced yearly (Ovam, 2016). This is 63 kg/capita or 8.5 % of the cement consumption.
The aim of this study is the development of a procedure for the recycling of the ferrous-nickel slag that is widely used in open dry blast cleaning operations in Greek shipyards thus annually ...
Ferrous slag output varies in proportion to crude iron and steel production. For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about 0.25 to 0.30 tons per ton of crude iron produced. ... Slag use is one of the great and relatively unsung stories of material reuse and recycling. Slags are coproducts of iron ...
During the BOS process a proportion of the molten iron cannot be recovered so elemental iron is often observed in the slag (Yildirim and Prezzi, 2011). Slags can be …
This End of Waste (EOW) code ferrous slag has been issued by the chief executive in accordance with section 159 of the Waste Reduction and Recycling Act 2011 (WRR Act). This EOW code states when the ferrous slag becomes a resource and any relevant requirements and/or
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. Entrained metal, particularly in steel slag, is routinely recovered during slag processing for return to the furnaces and is an important revenue source for slag processors ...
Ferrous slag is the term for the solid waste that is produced when raw iron is smelted in ironworks and during the production of steel. ... reducing emissions by reducing cement consumption and ...
The present paper analyses the current state of steelmaking slag recycling both in CIS and non-CIS countries. The accumulated experience of world practice in solving the problem of steelmaking slag recycling is described in detail. ... In particular, in Germany, the recycling of ferrous metallurgical slags has achieved a recycling level ...

1. Introduction. 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 …
Slags can be classified into three different categories: ferrous slag (contains iron), non-ferrous slag and incineration slag. The slag often contains a large amount of harmful and heavy metals, so the uses of slag has to be carefully managed to ensure no environmental impact ( Shen and Forssberg, 2003 ).
The inherent occurrence of slag "co-products" and its utilization during ferrous production are crucial for the industry to ensure greater sustainability. In this work, various research and technological developments to enhance the utilization of ferrous slag co-products and retrieval of thermal energy are reviewed.
