Sustainable Metal Recovery from Tailings

(Ref. BAP-2017-72)

Tewerkstelling : Voltijds
Duur : Bepaalde duur verlengbaar
Plaats : Leuven
Solliciteren tot en met : 01/04/2017
Since the earliest days of the Industrial Revolution, the primary mining and metal processing industry has been and still is landfilling and/or stockpiling vast quantities of metal-containing tailings. Especially the older tailing ponds and associated landfills may represent an environmental and health liability. However, the “tailings problem” can also be considered as an opportunity. By valorising historical and fresh tailings, an independent source of critical metals can be secured, hereby providing a more diversified and sustainable access to critical raw materials. However, traditional hydrometallurgical methods to recover metals from tailings involve the use of large quantities of concentrated acids or alkalis. Furthermore, such methods often require the re-landfilling of the residual fractions. More sustainable, comprehensive methods are required, which leach out the metals in a more eco-friendly way, while not jeopardising the valorisation solutions for the residual, mineral matrices. The SMART project aims to develop a generic toolbox for the sustainable recovery of metals from both historical and fresh tailings, using combinations of advanced hydrometallurgical, solvometallurgical and biometallurgical methods. After the metal extraction a clean mineral residue is left behind, which can be further valorised in construction materials or for rehabilitation of the mining site. KU Leuven is looking for a Post-doctoral researcher to work in a team of researchers at the Department of Chemistry. Your primary task is to deliver breakthrough solutions for sustainable metal recovery from tailings by non-aqueous leaching processes. Additionally, you critically think how the processes you develop can be implemented in an overall metallurgical flowsheet and how the process can be scaled up to an industrial scale. For this, you actively participate in discussions with the SMART partners (VITO, UGent, and Flamac) and with industrial partners (Jan de Nul – Envisan, Campine, Nyrstar, SGS Intron, Nucomat, MEAM, Sibelco and others). You also assist in elaborating follow-up projects aiming at the demonstration and industrial implementation of the developed tailings recycling flowsheets.
