SCALE was presented at the 3rd SLO Workshop Ensuring SLO is Adaptive and Resilient (5-6 June 2019, Brussels, Belgium), within the context of the MIREU project. The relevant lessons with regard to SLO, as well as additional aspects which affect the market deployment of the new technologies developed by SCALE, were presented to and discussed with an audience comprising other Eu projects,
Latest JRC science for policy report includes special chapter on the Bauxite Residue handling and recycling. The report, titled Recovery of critical and other raw materials from mining waste and landfills, focuses on the untapped potential to extract strategic raw materials from mining waste and landfills in Europe. The chapter, titled “Bauxite Residue as a resource in Europe”, gives the context of
The paper Re-using bauxite residues: benefits beyond (critical raw) material recovery, published in Journal of Chemical Technology & Biotechnology,s one of the journal’s top downloaded recent papers! See more SCALE publications
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).
