The slag's pouring is a processing step, and further processing (such as crushing the slag to form aggregate) is typically used, so the slag can undergo utilisation. Electric-arc furnace (EAF) steel-making uses high power electric arcs (instead of gaseous fuels) (Yildirim and Prezzi, 2011). EAFS is produced in an EAF, where the primary …
Current total productions of steel slag in India, are around 12 million tonnes per annum (Indian Minerals Yearbook, May 2016), …
Annually more than 400 Mt of metallurgical slags are produced worldwide [1,2,3,4,5].From the annual Cu concentrate smelter production capacity, which is equal to around 21 Mt of copper metal in 2021, it can be estimated that more than 45 Mt of CUS were produced from primary sources assuming a slag to copper ratio of 2.2 [3, 4].Only …
1. Introduction. Steel slag is the main solid waste generated in the steel-making process, accounting for 15 to 20% of crude steel output [1].China's crude steel output in 2021 was 1.035 billion tons [2], more than half of the global crude steel output (1.9505 billion tons) [3], and the steel slag output exceeded 120 million tons.In contrast, …
As the world's population grows and resource consumption rises, there will be an increase in waste and, consequently, the fly ash and slag from after the incineration of this waste need to be …

During steel production, the impurities in the hot metal react with the fluxes forming the steel slag. Chemical constituents of this steel slag (SS) are relevant to iron/steelmaking or blended cement manufacture. Harmful impurities present in it, however, limit its recycling to these applications. Japan, Europe, and the US consume a significant …
Despite some popular misconceptions, titanium is not a rare or an exotic element; in fact, it is the ninth most abundant element on earth's crust, with an average abundance estimated between 0.3% and 0.9% wt. [1], [2].Because of its strong affinity with oxygen, titanium's most common minerals are oxides [3].These minerals (Fig. 3.1) …
With world steel production now well over a billion tonnes per year, the slag that arises from some of the processes involved is a major resource. Traditionally it has been used mainly as an aggregate but for some types there are other applications, such as a raw material for cement or as a fertiliser.
