Disintegration of Six Different Quartz Types during Heating to 1600 °C
(Journal article; Peer reviewed, 2023) -
The Effect of Pre-Oxidation on the Reducibility of Chromite Using Hydrogen: A Preliminary Study
(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 ... -
Effect of Raw Materials on Temperature Development during Prereduction of Comilog and Nchwaning Manganese Ores
(Peer reviewed; Journal article, 2023)The effect of raw materials on the temperature development and prereduction behavior of Comilog and Nchwaning manganese ores (3.33–4.00 mm or 11.20–15.00 mm) were investigated in a CO-CO2 atmosphere. Experiments were ... -
An Invitation on Characterization of H<inf>2</inf>-Reduced Bauxite Residue and Recovering Iron through Wet Magnetic Separation Processes
(Peer reviewed; Journal article, 2023)Recovering iron from the bauxite residue (BR) is one of the long-standing challenges in the mining industry. However, there is a substantial lack of information in the literature regarding sample properties and iron ... -
An Overview of Currently Applied Ferrochrome Production Processes and Their Waste Management Practices
(Peer reviewed; Journal article, 2023)Ferrochrome (FeCr) is the main source of virgin chromium (Cr) units used in modern-day chromium (Cr) containing alloys. The vast majority of produced Cr is used during the production of stainless steel, which owes its ... -
Prereduction of Nchwaning Ore in CO/CO2/H2 Gas Mixtures
(Peer reviewed; Journal article, 2021)Prereduction of Nchwaning manganese ore was investigated by isothermal reduction between 600 and 800 °C to optimize the conditions for industrial pretreatment of manganese ores. Experiments were conducted in CO/CO2 gas ... -
Reduction and Dissolution Behaviour of Manganese Slag in the Ferromanganese Process
(Journal article; Peer reviewed, 2020)The reduction and liquidus behaviour of manganese slag with different basicities were studied in non-isothermal experiments in the temperature range of 1400–1500 °C. Certain amounts of quartz were added to Assmang ore ... -
The use of hydrogen as a potential reductant in the chromite smelting industry
(Peer reviewed; Journal article, 2022)The chromium (Cr) content of stainless steel originates from recycled scrap and/or ferrochrome (FeCr), which is mainly produced by the carbothermic reduction of chromite ore. Ever-increasing pressure on FeCr producers to ...
