Third progress meeting held in Poland

ENSUREAL‘s consortium reconvened in Poland, on the 19th and the 20th of March 2019, for the third progress meeting. The meeting, hosted by Odlewnie at the Polish Foundry of Starachowice, focused on the progress achieved in the last few months in the various work-packages, as well […]

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 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 process can be […]

NTUA Hydrometallurgical Work Update

Following the large scale smelting experiment in Trondheim last September, NTUA has received a significant amount of Calcium Aluminate Slags. The research team, consisting of Mr. Michalis Vafeias and Mrs. Maria Bagani, are proceeding with the characterization and hydrometallurgical treatment of the aforementioned slags.  Specifically, during the past two weeks, work has focused on defining the […]

ENSUREAL presented at H2020 Innovation Forum

On October 4th, 2018 ENSUREAL took part in the first H2020 Innovation Forum, a clustering event, bringing together H2020 projects, but also policy makers, end-users and industry representatives, material producers, private and public investors, start-ups and innovative SMEs. Casper van der Eijk from Sintef, project co-ordinator, presented ENSUREAL within the […]

Second progress meeting held in Athens

NTUA hosted ENSUREAL‘s second project meeting on October 2-3, in Athens, Greece. 24 representatives of 12 partners met to discuss the project’s progress, and organise the next steps. The results of the first pilot tests were showcased, as well as the publications from the first few […]

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 […]

Bauxite smelting experiment

Ingeborg Solheim (SINTEF) and Mado Ladou (NTNU) are smelting bauxite in an open induction furnace. During the trial, they take samples of the slag to understand more about the kinetics of the reactions that take place.

ENSUREAL research presented @ BR2018

ENSUREAL participated in BR2018, the Bauxite Residue Valorisation and Best Practices Conference that took place in Athens, on May 7-10 2018. In the context of ENSUREAL, Michal Ksiazek from SINTEF, presented a paper titled “Iron removal from bauxite ores“. Download the presentation / paper Michail Vafeias from NTUA, presented […]
