A XANES Study of Sulfur Speciation and Reactivity in Cokes for Anodes Used in Aluminum Production
(Journal article; Peer reviewed, 2018)Availability of anode raw materials in the growing aluminum industry results in a wider range of petroleum cokes being used to produce carbon anodes. The boundary between anode grade cokes and what previously was considered ... -
An EXAFS and XANES Study of V, Ni, and Fe Speciation in Cokes for Anodes Used in Aluminum Production
(Journal article; Peer reviewed, 2019)Lower-quality petroleum coke with higher levels of sulfur and metal impurities will have to be used for the manufacturing of anodes for aluminum production in the future. The sulfur and metallic impurities affect the anode ... -
Characterization of a Si-SiO2 mixture generated from SiO and CO
(Peer reviewed; Journal article, 2019)The reaction between SiO(g) and CO(g) is a relevant intermediate reaction in the silicon production process. One of the products generated from this gas mixture is called by its color, brown condensate. In this paper, ... -
Damring formation during rotary kiln chromite pre-reduction: Effects of pulverized carbonaceous fuel selection and partial pellet melting
(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 ... -
Element distribution in the silicomanganese production process
(Peer reviewed; Journal article, 2018)A pilot scale, silicomanganese alloy production campaign was performed in a 440 kVA, single phase electric furnace in order to establish an overview of the minor- and trace element contents in process input raw materials ... -
In situ monitoring of pit gas composition during baking of anodes for aluminum electrolysis

The Mechanism Behind the Oxidation Protection of High Mg Al Alloys with Beryllium
(Peer reviewed; Journal article, 2018)The addition of beryllium to Al-Mg alloys is known to cause a dramatic decrease in oxidation; however, the mechanism behind this protective effect is not yet fully understood. To aid in finding an alternative to the toxic ... -
Ore melting and reduction in silicomanganese production
(Peer reviewed; Journal article, 2010)The charge for silicomangansese production consists of manganese ore (often mixed with ferromanganese slag) dolomite or calcite, quartz, and in some cases, other additions. These materials have different melting properties, ... -
Thermodynamic and Kinetic Behavior of B and Na Through the Contact of B-Doped Silicon with Na2O-SiO2 Slags
(Peer reviewed; Journal article, 2013)Boron (B) is the most problematic impurity to be removed in the processes applied for the production of solar grade silicon. Boron removal from liquid silicon by sodium-silicate slags is experimentally studied and it is ...
