Basic oxygen steelmaking (BOS) slag, a product of hot metal element (e.g., Si, Mn, Fe, P) oxidation and flux (e.g. lime, dolomite) dissolution, plays a critical role in the production of high-quality crude steel, although its behavior inside the BOS vessel (formation and reaction with metal droplets and gas) is still not clear and its recycling has always been challenging.
In 2017, Japan claimed ~ 14 million tonnes of steel slag production, while China reported 100 million tonnes of steel slag in the year 2016 [2, 3], which is in line with the available data of 10 to 15% of waste by-product during steel production . The percentage of slag production directly depends upon the steel-making processes.
