The flexibility of the process allows obtaining granules of different sizes and with different ratio between crystalline and amorphous phases to respond at the request of the final user.This innovative process …

 — 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 …

 — In stainless steel production, slag from argon oxygen decarburization (AOD) converters is dumped on to the ground and then slowly cooled. The slag undergoes phase transformation from β-dicalcium silicate (β-C2S) to γ-dicalcium silicate (γ-C2S) at approximately 500 °C to 450 °C, resulting in slag volume expansion, disintegration, and …
