GDR Prométhée – French Research Network on Hydrometallurgical
Processes for Primary and Secondary Resources
Special issue on hydrometallurgical processes for the
integrated management of primary and secondary
resources: Foreword
Laurent Cassayre and HervéMuhr
This special issue is the initiative of the Prométhée
GDR, a national research group dedicated to the
study of hydrometallurgical processes for the inte-
grated management of primary and secondary re-
sources. This GDR was created in January 2016 and
renewed in 2021, and brings together around 150 re-
search actors from 27 academic laboratories, as well
as CEA, IFPEN and BRGM teams. It contributes to
structure French research community on hydromet-
allurgical processes, for a better management of non-
energy mineral resources, from mining to recycling.
The CNRS, via its two institutes “Chemistry” and “En-
gineering”, is funding this GDR.
The community was invited to submit part of their
work for this special issue of the journal Comptes
Rendus de l’Académie des Sciences. Following a
standard review process, 13 of these articles have
been published, among which four review articles
and nine research papers. They cover and com-
bine a wide range of scientific fields, from chemi-
cal engineering, separation chemistry, electrochem-
istry, biometallurgy, physical chemistry or mechano-
chemistry, and address a various range of metal el-
ements, such as noble metals, transition metals,
lithium, rare earths, uranium and actinides. More
specifically, this special issue starts with a presen-
tation of a specific classification process for elec-
tronic wastes [1]. Then four articles are dedicated
to leaching and bioleaching processes [2–5], three
articles deal with both leaching and precipitation
operations [6–8], two focus on precipitation [9,10],
two consider chemical aspects of solvent extrac-
tion [11,12] and a last paper is dedicated to elec-
trometallurgy of noble metals in deep eutectic sol-
vents [13].
We would like to thank all authors for their impli-
cation in this Special Issue, as well as the >30 review-
ers who provided many valuable insights on these
papers.
