Slag production pilot

The pre-reduced bauxite that was produced in the hydrogen pre-reduction test, was used in a second pilot experiment in Sintef, to produce slag. In this case, the production of the slag was easier than with the raw bauxite because many chemical reactions were already finished during […]

Hydrogen prereduction of bauxite

During the most recent ENSUREAL test run, 500 kg of AoG bauxite were successfully bauxite were successfully pre-reduced in hydrogen at the SINTEF pilot plant. The test was done in a plasma heated rotary furnace, that only uses electricity for heating. In this set-up, the Pedersen […]

Pyrometallurgical method pilot tests

The ambition of the ENSUREAL project is to demonstrate that a modified version of the Pedersen process can produce alumina from a wide range of minerals while not producing any waste materials. In September 2018, Sintef and NTUA tested the pyrometallurgical method in a series of […]
