Steel industries are moving towards sustainable utilisation of their waste as co-products. • Slag sources, properties, and studies of beneficial application are reviewed. ... This review aims to examine various slag generation processes in steel plants, their physicochemical characteristics in relation to beneficial utilisation as a soil ...
Slags are by- or co-products of the iron and steel making process. BF (blast furnace) slag is generated in iron production and EAF (Electric Arc Furnace) slag is generated by steel production. The same is with Basic Oxygen Furnace (BOF) slag. Processing of EAF using traditional methods involves crushing and grinding.
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 …
On January 16, 1918, an organizational meeting of slag processors was scheduled at 3:30 pm at the Chittenden Hotel, Columbus Ohio. A total of 13 slag processing companies were represented at this meeting in addition to press and trade journal representatives from Rock Products and Building Materials, Pit and Quarry, and staff from the Ohio State Journal.
