Exploitation of the ENSUREAL results

Precipitation of alumina hydroxide

The precipitation equipment at NTNU.

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 function of the temperatures and CO2 concentration.
