(PDF) BOF Slag: Turning Waste Into Value
Abstract Basic oxygen furnace slag (BOF slag) is an unavoidable by-product of steelmaking process of basic oxygen furnace. The value of the slag as a secondary raw material depends of the final application and the processing costs. The critical factor is the cost of the valorization process, consisting of total process energy Slag recycling and reuse GREENY approach

Occurrence of steel converter slag and its high value-added
The high impact and crushing values of converter slag, along with its rough surface roughness, define its high level of strength Regarding organic pollutants, researchers have demonstrated that the steel converter slag as a low-cost adsorbent has a certain adsorption capacity for phenanthrene, naphthalene, and phenol (Sarkar et al.,7. Conclusion and future work. Steel Slag contains valuable metals like iron, nickel, magnesium, aluminium, vanadium and titanium. While vanadium and titanium, are available in small quantities, their high value and limited available resources can offset the total expenditure incurred during their extraction from SS.Waste to wealth: Recovery of value-added products from steel slag

Steel slag in China: Treatment, recycling, and management
In this paper, we reviewed steel slag treatment, recycling, and management in China. Although China’s annual slag production reached more than 100 million tons, its utilization rate is only 29.5%. As of 2016, more than 300 million tons of steel slag have not been used effectively. Large steel slag emissions are causing environmental problemsDuring 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.

Steel slag in China: Treatment, recycling, and management
Typically, slag material that is larger than 25.4 mm in diameter is highly metallic and recycled as scrap. The finer the particle size, however, the higher the recycling rate of magnetic content and the greater the recycling cost. Fine steel slag below 12.5 mm is the most difficult to utilize, partly because of its high impurity concentration.The studies showed that in the case of the charge chrome plant, crushing of mixed metal and slag to below 10 mm followed by jigging of the −10+1 mm material and tabling of the −1 mm material would help recover 10 tpd of metal from the 18 tpd of mixed metal. Based on the studies, a plant is now operational at the Ferro-Alloy Plant (FAPRecovery of metal from slag/mixed metal generated in
