Can the ENSUREAL process be used to capture CO2 from furnace off-gas?

In the ENSUREAL process, bayerite is precipitated with CO2 after the slag has been leached. The ENSUREAL team is now doing experiments to investigate whether this precipitation can take place using off-gas with a CO2 concentration as low as 5%. If this is possible, then the process could […]

ENSUREAL’s results presented in BR2020 Conference

ENSUREAL partners presented some of the results from ENSUREAL project in the  3rd International Bauxite Residue Valorization and Best Practices Conference in September 2020. The goal of this conference is to search realistic and scientific solutions for Bauxite Residue. Three were the sessions dedicated to ENSUREAL:

ENSUREAL produces grey mud

The ENSUREAL process has a by-product called grey mud. It is mostly limestone which can be used as a building material. In the project the grey mud is tested as building material in the SINTEF Laboratorium.

First Pilot scale test at MYTILINEOS for production of slag and cast iron

After months of delay due to COVID-19, finally the first pilot scale test at the industrial complex of Aluminium of Greece at Agios Nikolaos, Viotia was done. Bauxite residue was mixed with lime to produce iron and slag. The iron can be used as cast-iron and […]

Exploitation of the ENSUREAL results

Within the ENSUREAL project, several locations for a full-size alumina plant are being considered. One of these is Mo Industrial Park, one of Norway’s largest industrial parks, situated in the town of Mo i Rana. The site is attractive because of: The nearby presence of an […]

Precipitation of alumina hydroxide

After leaching of the slag in the ENSUREAL process, aluminium hydroxide is precipitated through bubbling of CO2 through the solution. At NTUA in Athens and NTNU in Trondheim, the groups are working on the precipitation stage of the process. The efficiency of the precipitation is tested as […]

Induction furnace experiments at NTNU

Jafar Safarian, James Mwase and Adamantia Lazou working in the lab. First picture of them weighing the raw materials. They are mixing bauxite residue and quick lime. The goal is to produce slag that can be leached at NTUA. The second picture is Jafar checking the […]

4th project meeting completed

ENSUREAL‘s 4th project meeting was held at the Norway House in Brussels, on the 1st and 2nd of October, 2019.
