The 5th Progress meeting was held at FHNW in Basel, Switzerland on the 28-29 May 2019

II-VI has successfully demonstrated its SIR process in pilot scale by processing 1.9 m3 of acid waste stream from TRONOX and producing 1.3 kg of crude scandium oxide concentrate. This is the first case of Sc oxide production from European industrial waste stream. The SIR pilot plant was subsequently been transferred to Mytilineos – Aluminium of Greece refinery where it

MEAB GmbH will set-up their solvent extraction bench scale demonstration plant in Aachen, Germany. Working with scandium hydroxide produced from Tronox acid waste solution using II-VI SIR pilot plant, they will conduct main operation steps: 1) Dissolution and impurity hydrolysis, 2) Scandium solvent extraction, and 3) Precipitation of ammonium-scandium-hexafluoride by anti-solvent addition. This method has been developed by MEAB engineers

META Nikel-Kobalt A.Ş produced their first Scandium product using MEAB’s solvent extraction mixer-settler mini-pilot plant. Scandium was separated from a Nickel and Cobalt HPAL production plant in Gördes, Turkey. META produced about 600 grams of Sc product in the form of Ammonium-Scandium-Hexafuoride ((NH4)3ScF6). After calcination, they also converted (NH4)3ScF6 to Scandium fluoride (ScF3) suitable for molten salt or metallothermic reduction.

A team from NTUA Laboratory of Metallurgy and Mytilineos, Metallurgy Business Unit has been awarded the 2019 Light Metals Subject Award – Alumina/Bauxite for its innovative work “Developing a new process for selective extraction of Rare Earth Element from Bauxite Residue based on factionlized ionic liquids”.

The SCALE pilot plant uses ionic liquid to extract rare earth elements from the bauxite residue (red mud) of alumina production.

The Critical raw materials data management & European scandium inventory workshops took place with great success, in Berlin, Germany, on 26-27 November 2018. The workshops were co-organised by SCALE and the German Federal Institute for Materials Research and Testing (BAM). To download the presentations and view photos from the events, please visit the Workshop Results page.

The 4th progress meeting was held at BAM in Berlin on the 28th of November. At the 2 year mark of the project, all research streams have produced significant results and the SCALE pilot facilities are being commissioned according to plan.

On October 4th, 2018 SCALE 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. Thymis Balomenos from Aluminium of Greece, project co-ordinator, presented SCALE within the context of the clustering session, to an audience comprised by other H2020 projects,
