Recovery of Iron and Aluminum from Bauxite Residue by Carbothermic Reduction and Slag Leaching
(Peer reviewed; Journal article, 2021)The recovery of major components of bauxite residue by carbothermic reduction at 1550–1750 °C and subsequent slag leaching in a Na3CO3(aq) solution is studied. Iron recovers primarily to pig-iron and lime is added to tune ... -
Recovery of Platinum Group Metals From Secondary Sources by Selective Chlorination from Molten Salt Media
(The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2020)The use of molten salts as “solvents” offers interesting possibilities for the treatment of ores, industrial by-products as well as scraps, allowing the development of processes that are mid-way between pyro- and ... -
Recycling of the Flue Gas from Aluminium Electrolysis Cells
(The Minerals, Metals & Materials Series;2367-1181, Chapter; Peer reviewed, 2020)Recycling of the flue gas from aluminium reduction cells is a possible method for increasing the CO2 concentration, thereby enabling CO2 capture. The present paper represents a preliminary study concerning some of the ... -
Recycling of the Rare Earth Oxides from Spent Rechargeable Batteries Using Waste Metallurgical Slags
(Journal article; Peer reviewed, 2013)A high temperature process for recycling spent nickel-metal hydride rechargeable batteries has been recently developed at SINTEF/NTNU. The spent battery modules were first frozen with liquid nitrogen for the de-activation ... -
Self-Reinforced Polypropylene Composites based on Discontinuous Tapes - An Experimental and Numerical Study of the Influence of Tape Length
(Peer reviewed; Journal article, 2020)The creation of highly oriented, coextruded polypropylene (PP) tapes allows the production of recyclable self-reinforced polypropylene (SRPP) or all-PP composites, with a large temperature processing window and high volume ...
