Unique challenges of clay binders in a pelletised chromite pre-reduction process.
(Elsevier, 2012)Ferrochrome producers strive towards lower overall energy consumption due to increases in costs, efficiency and environmental pressures. In South Africa, in particular, higher electricity prices have placed pressure on ... -
Unique challenges of clay binders in a pelletised chromite pre–reduction process : a case study
(North-West University, 2011)As a result of increasing cost, efficiency and environmental pressures ferrochrome producers strive towards lower overall energy consumption. Increases in local electricity prices have placed particular pressure on South ... -
The use of hydrogen as a reductant in the smelting industry
(North-West University (South Africa), 2022)Both the smelting of chromite and manganese (Mn) ores consume a significant amount of carbon (C) and electrical energy. The smelting processes contribute to the elevation of carbon dioxide (CO2) emissions in the atmosphere ... -
Utilisation of pre-oxidised ore in the pelletised chromite pre-reduction process
(Elsevier, 2016)Ferrochromium is a vital alloy mostly used for the production of stainless steel. It is produced from chromite ore, the only economically exploitable natural chromium resource, through carbothermic smelting in submerged ... -
Why is CaCO3 not used as an additive in the pelletised chromite pre-reduction process?
(Elsevier, 2013)The production of ferrochrome is an energy intensive process. At present, the pelletised chromite pre-reduction process is most likely the ferrochrome production process with the lowest specific energy consumption, i.e. ...
