In this study, a novel process for recovering Cr from Cr-bearing electroplating sludge (ES) was proposed, which involved the desulfurization stage and reduction-smelting stage. stage, decomposition of CaSO4 in ES promoted by adding certain amount carbon. It found that ratio increased first then decreased as increasing C/S (molar ratio) 0.5 to 2, while it monotonously temperature raised. The pro...

Abstract Direct emissions due to the use of carbon-based fossil-reducing agents contribute overall CO 2 pyrometallurgical production processes. This study investigated replacement fossil coke by silicon-rich cutting waste from solar wafer process produce ferrochrome in an electric arc furnace. Laboratory test work and thermochemical simulation were carried out examine product quality at various...
