Damring formation during rotary kiln chromite pre-reduction: Effects of pulverized carbonaceous fuel selection and partial pellet melting
van Staden, Yolindi; Beukes, Johan Paul; van Zyl, Pieter Gideon; Ringdalen, Eli; Tangstad, Merete; Kleynhans, Ernst L.J.; Bunt, John Reginald (Peer reviewed; Journal article, 2018)Electricity consumption is the largest cost contributing factor in the production of ferrochrome. Currently the pelletized chromite pre-reduction process (solid-state reduction of chromite) is the process option with the ... -
The Effect of Pre-Oxidation on the Reducibility of Chromite Using Hydrogen: A Preliminary Study
Davies, Jamey; Tangstad, Merete; Ringdalen, Eli; Beukes, Johan Paul; Bessarabov, Dmitri; du Preez, Stephanus Petrus (Peer reviewed; Journal article, 2022)The majority of ferrochrome (FeCr) is produced through the carbothermic reduction of chromite ore. In recent years, FeCr producers have been pressured to curve carbon emissions, necessitating the exploration of alternative ...
