Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basic-oxygen-furnace (BOF) steelmaking, electric-arc-furnace (EAF) steelmaking, and ladle-furnace steel refining processes. The mineralogical and morphological properties of …
Currently the steel industry is among the three biggest producers of carbon dioxide, with emissions being produced by a limited number of locations; steel plants are therefore a good candidate for decarbonization.
Recycling of steel slag In a steelmaking plant, the raw material used in the form of steel scrap, which contains a large number of impurities (gangue). For converting steel scrap into useful steel billets, a flux is used to remove impurities present in it. Flux reacts with gangue and removes it in the form of slag, which is known as steel slag.
While most of the furnace slag is recycled for use as an aggregate, excess steel slag from other operations (raker, ladle, clean out, or pit slag) is usually sent to landfills for disposal. MARKET SOURCES Steel slag can …

The steel industry needs scrap to produce new steel, which ensures that all steel products contain anywhere from 25 percent up to 100 percent recycled content. It also is cheaper to recycle steel than it is to mine ore to manufacture new steel. New ore is still mined in order to supplement production of steel and steel products.

Slag, the main by-product, can be used to make cement, where it reduces CO2 emissions by around 50%. It is also used in road-making, as a fertiliser (it is rich in phosphate, silicate, magnesium, lime, manganese and iron), and in coastal marine blocks that …
Reducing our environmental footprint. ArcelorMittal Tubarão sells about 200,000 tonnes of slag to the cement industry every year and can save up to 700kg of carbon dioxide (CO 2) emissions for every tonne of granulated slag that is re-used in concrete. Following the success of the recycling project at Tubarão, our steel unit in Asturias ...
