Students extracting metals from Red Mud

Meet Olivia Bogen Skibelid, Frida Vollan and Sander Ose Velle! They are chemistry students at NTNU doing their Bachelor on extracting metals from Red Mud. Red Mud, or bauxite recidue, is a waste product produced by the aluminium industry. Global annual production of red mud (bauxite residue) is about 150 million tonnes. It contains varying […]

Oral presentation at TMS2022

Oral presentation at TMS2022 HARARE was presented at the TMS2022. TMS is the annual meeting and Expedition of The Minerals, Metals & Materials Society that brings together engineers, scientists, business leaders, and other professionals in the minerals, metals, and materials fields for a comprehensive, cross-disciplinary exchange of technical knowledge. This year’s meeting was held in person […]

Recovery of Copper, Iron, and Alumina from Metallurgical Waste by Use of Hydrogen

Recovery of Copper, Iron, and Alumina from Metallurgical Waste by Use of Hydrogen Abstract: Substituting carbon with hydrogen is one of the few ways metal production can potentially become free of CO2 emissions. Moreover, the metallurgical industry produces significant amounts of waste. The present work presents a circular concept that will be pursued in the HARARE […]

Hydrogen reduction in molten copper

Hydrogen reduction in molten copper Meet Gunnar Hovestadt! He is a Ph.D. student at RWTH Aachen and is dealing with hydrogen reduction in molten state. He is part of the copper reduction team and supervises several student thesis in our project.  With his Ph.D. topic Gunnar wants to develop new reduction processes with hydrogen to reduce […]

How to extract iron from Red Mud

How to extract iron from Red Mud Meet Arman H Kermani (to the right) and Per Ivar Friborg (to the left) from NTNU doing small scale experiments at a SINTEF facility. The aim of these experiments, conducted by Arman, is to be able to reduce red mud with hydrogen, producing iron. Red Mud is a […]

Hydrogen as reductant – What does that mean?

Hydrogen as reductant – What does that mean?   Metals exist in the earth’s crust mainly as oxides. It means that every metal atom is attached to one or more oxygen atoms. They form very strong bound, like a marriage. To break these bounds, we need a reductant to steal the oxygen atoms from the metal atoms. Normally carbon is used […]

Let’s talk about Red Mud (Bauxite Residue)

Let’s talk about Red Mud (Bauxite Residue) Global annual production of red mud (bauxite residue) is about 150 million tonnes. It contains raw materials for the production of iron, silicon and aluminium, and is dumped as waste in spite of the availability of recycling technologies. This is because it is cheaper to dump bauxite residue as […]

HARARE Kick-off

The HARARE project successfully kicked off on June 7th, 2021 when the project partners came together for a virtual meeting. The event was hosted by SINTEF. The project is coordinated by Senior scientist Casper van der Eijk. During one long day, the partners reviewed the objectives of the project and planned actions to begin the […]
