=== Reduction ===
After a desired carbon and temperature level have been reached the process moves to reduction. Reduction recovers the oxidized elements such as chromium from the slag. To achieve this, alloy additions are made with elements that have a higher affinity for oxygen than chromium, using either a silicon alloy or aluminium. The reduction mix also includes lime (CaO) and fluorspar (CaF<sub>2</sub>). The addition of lime and fluorspar help with driving the reduction of Cr<sub>2</sub>O<sub>3</sub> and managing the slag, keeping the slag fluid and its volume small.
=== Desulfurization ===
