Fifty Shades of Recovered Metal

The "Fifty Shades of Grey" Union Jack

Cementation is defined as the precipitation of a noble metal when it comes into contact with a less noble one. Since Roman times, this process has been applied in many metallurgical industries for contact plating, recovering valuable metals from waste solutions etc. However it has never been used before for painting! Stelios (ESR 5), in his research towards the selective ...

The unsung heroes of copper electro-refinery

Figure 1: Copper electrorefining tankhouse (https://copperalliance.org.uk/)

Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity and because of these properties, it is the undisputed material of choice for conducting electricity. The quality of the copper should be very good for electrical applications. Bad quality dramatically changes the electrical conductivity and workability. The following qualities are important for copper; Chemical property: ...

Advanced characterization and integrated assessment of WP4

apple-icon-144x144

WP4 is an integrative WP, which interacts closely with WP1–3 and provides a truly interdisciplinary, systems approach. There are 2 ESRs in WP4, ESR14 and ESR15. Two main elements are targeted: advanced characterization and integrated assessment. ESR14 will perform advanced characterization of the industrial-process residues to find out which mineral phases the metals occur, how these phases are distributed throughout ...

Gamechangers: ESRs of WP3 works on residual matrix valorization

SOCRATES WPs

Hello all, We are the researchers of Work Package 3 (WP3) of the SOCRATES project working on ‘Residual matrix valorization’. In today’s business-as-usual setting, a low-grade, solid or slurry, industrial-process residue remains after the recovery of the valuable metals. This solid residue is normally stored in tailing ponds, landfilled or, at best, the coarse fractions are used as an additive ...
