Contenus de l'unité d'enseignement

The course has objective to enlarge the knowledge of the students following mining-geological engineering and chemical and materials engineering (AMIR) study tracks towards the contemporary and emerging metallurgical processes used for production of the main non-ferrous (Cu, Zn, Pb,..), critical (Co, Ni, Mn) and precious metals. The course covers both the theoretical aspects of modern extractive metallurgical processes as well as refers to selected case studies. It encompasses the core units listed below :

Metallurgical processes for production of the main non-ferrous metals

Leaching chemistry - Kinetics and Mechanisms.
Hydrometallurgy of main mineral ores
Treatment of productive solutions after leaching
Electrometallurgy (electro refining)
Reactive extraction and liquid membranes
Hydrometallurgical advances in processing of "critical" metals from EoL products

The course begins with an introduction to metallurgical processes enabling the students to get aware about the challenges in metals extraction and purification processes from both technological as well as an economical points of view. The basics of chemical thermodynamics related to mineral compounds stability in aqueous systems follows. The theoretical grounds of the modern hydrometallurgy are presented together with examples of operational flowsheets for leaching common mineral ores and concentrates. The way of treating pregnant leach solutions (PLS) after leaching are equally discussed, followed by the basics of electrorefining, reactive extraction and liquid membrane possesses as supplementary methods. The practical application of the latter techniques is likewise illustrated as part of the contemporary strategies in recovery of "critical" metals from EoL (End-of-Life) products. Case studies with reference to the economical parameters (metals recovery, purity of final products) which cover selected hydrometallurgical operations (heap-leaching of precious metal ores, processing of nickel laterite, Ni/Co and Cu/Co ores) are presented

The laboratory classes include exercises relative to mineral equilibrium systems (Pourbaix diagrams using HSC Chemistry), theoretical calcualtions of mass transfer and preparation and hydrometallurgical processing of e-waste materials with associated mass balance calculations.

Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

By the end of this course, a student should be able to:

Understand the origin of metal value from process chain point of view
Determine the correct stoichiometry for a metal leaching reaction
Understand the thermodynamics of ideal mixtures and calculate phase compositions of mineral-solution systems at equilibrium
Understand the main stages involved in the hydrometallurgical processing of non-ferrous metal ores
Get aware about hydrometallurgical advances in recovery of critical metals from EoL streams

Ce cours contribue aux acquis d'apprentissage I.1, I.2, II.2, II.3, III.2, III.4, IV.2, IV.3, VI.1, VI.2, VII.1, VII.2, VII.3, VII.4, VII.5 du programme d'ingénieur civil des mines et géologue.

Savoirs et compétences prérequis

It is advisable that the students possess knowledge on raw materials value chain, chemical thermodynamics and are aware of the basic principles of process engineering

Activités d'apprentissage prévues et méthodes d'enseignement

Theoretical lectures and laboratory exercises. The lab exercises involve: mineral chemical reactions (hydrometallurgy) (HSC Chemistry), preparation of "e-waste" material, leaching and solution processing. Single-drop experiments for determining mass-transfer rate.

Remarques organisationnelles et modifications principales apportées au cours

Ce cours est programmé au prémier quadrimestre

Jeudi pm;

Ce cours presente l'integralité de procedés qui font partie de la chaine finale de la production industrielle de métaux. Ainsi, bien qu'un lien existe, la matière abordée dans ce cours se distingue de celle déjà vue dans les cours Mineral Processing et Soild Waste and By-product processing. Les principes théoriques de la metallurgie extractive sont largement presentés et des excercises sur ordinateur ou en laboratoire permettent aux étudiant(e)s de mieux comprendre la matiére.
