Slag is the by-product of iron- and steelmaking processes. Normally, around half to one tonne of slag would be generated for yielding one tonne of rolled iron or steel (Lobato et al. 2015).It was reported that the world steel production was 1.9 billion tonnes in 2016, which suggested that at least around 1 billion tonnes of slag is produced during …
Mineral process wastes, such as metallurgical slags nowadays, are of significant metals and materials resources in the circular economy. The usability of iron-making slag is well established; however, steel slag still needs to be utilized due to various physicochemical constraints. In this context, we have reviewed the global steel slag …
Applications of Slag Crusher Machines Steel Industry. Slag Crusher Machines are widely used in the steel industry for the processing of slag generated from the iron and steelmaking process. The crushed slag can be used as a raw material in steelmaking, reducing the need for raw materials and decreasing the carbon …

The internal recycling process of BOF slag which is one of the huge solid wastes from iron and steel industry was emphasized. Based on the four scenarios of different internal recycling strategies for BOF slag, life cycle assessment (LCA) as a valuable tool for industrial solid waste management was applied to analyze the …
The smelting slag mentioned above refers to iron capture smelting slag. Compared with other metals, iron capture is a cost-effective and environmentally friendly method. Among the various iron capture methods, plasma smelting is more efficient [32]. However, this method faces several challenges, including the need for significant equipment ...
Steel slag is the waste slag produced in the steelmaking process, and its output is 15%-20% of the crude steel output, and it accounts for a large proportion of the industrial waste slag.
Converter off-gas, an important energy resource for steel industries, is one of the weak points in the recovery and utilization of secondary energy resources. To improve the level of recycling converter off-gas in steel plants, a novel approach to the recycle of CO2 separated from converter off-gas or other off-gas for the green slag splashing …
