High silicon iron alloy from bauxite residue
Bauxite residue (BR) contains typically 20 to 50% iron oxide. A full valorisation of the BR requires that this iron is returned to the market. It is not difficult to recover this iron as pig iron, but the market price for pig iron is too low to make this economically viable. Iron alloys with high...
On the Direct Reduction Phenomena of Bauxite Ore Using H2 Gas in a Fixed Bed Reactor
Smelting reduction of bauxite residue and beneficiation by-product in view of a leachable slag and pig Iron production
Results of three H2020 projects dealing with bauxite residues.
Reduction of Mixtures of Ni-Oxide and Ti-oxide powder in a natural gas containing atmosphere
Natural gas has been used as reductant in the production of iron for several decades. Recently, the use of natural gas as reductant for other metals has been drawing attention because of the low price of natural gas, as well as the reduction of CO2 emissions compared to the use of coke and coal. In...
Recycling the Rare Earth Elements from Waste NiMH Batteries and Magnet Scraps by Pyrometallurgical Processes
Recycling of the Rare Earth Oxides from Spent Rechargeable Batteries Using Waste Metallurgical Slags
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 and brittle fracture treatment. The broken steel scraps and plastics were then...
Fracture of notched round-bar NiTi-Specimens
In this work fractography has been used to characterize the fracture surfaces of superelastic, notchedround-barNiTi-specimens. Several fractography studies have been performed for conventional materials, but only few studies have been conducted on NiTi-alloys. The aim of this work is to investigate...
