CHEM ENG 4058 - Hydrometallurgy and Electrometallurgy
North Terrace Campus - Semester 2 - 2021
General Course Information
Course Code CHEM ENG 4058 Course Hydrometallurgy and Electrometallurgy Coordinating Unit School of Chemical Engineering Term Semester 2 Level Undergraduate Location/s North Terrace Campus Units 3 Contact Up to 4 hours per week Available for Study Abroad and Exchange Y Course Description This course aims to provide the Chemical Engineering Minerals Processing students with an understanding of hydrometallurgy and electrometallurgy techniques that are used in the processing of minerals. The main topics covered in hydrometallurgy include acid, alkaline and pressure leaching, thermodynamic and kinetic aspects of leaching, purification of leach liquors by ion exchange, solvent extraction, adsorption using active carbon, selective precipitation operations, and solid-liquid separation techniques. Several practical processes are studied including heap and tank leaching, copper extraction, nickel, zinc, cobalt, gold and uranium processing etc. The main topics in electrometallurgy include Pourbaix diagrams, recovery of metal values by cementation, electrowinning and refining from aqueous solutions, electrolyte preparation, cell potential, effect of additives, aluminium smelting from molten salt electrolytes, design of electrochemical reactors and application of processes for the recovery of copper, zinc, gold and aluminium. At the end of this course you should be able to demonstrate a good understanding of the key factors that govern the successful operation of hydrometallurgical and electrometallurgical processes in the minerals industry.
Course Coordinator: Dr Neil Smith

Course Learning OutcomesOn successful completion of this course students will be able to:
1 Explain the driving forces behind the thermodynamics of leaching and how it impacts the design of a hydrometallurgical process; 2 Explain the driving forces behind the kinetics of leaching and how it impacts the design of a hydrometallurgical process; 3 Explain the various methods and practices of leaching, including basic design principles; 4 Explain the concepts of solids/liquids separation and how to apply to a process; 5 Discuss the concepts and design of separation and purificaiton including; solvent extraction; ion exchange; precipitation; crystallisation; and membrane treatment; 6 Explain the concepts and design of metal recovery processes including; cementation; reduction; electrowinning and electrolytic refining; and precious metal recovery; and 7 Apply the material learnt to a flow sheet design.
The above course learning outcomes are aligned with the Engineers Australia Stage 1 Competency Standard for the Professional Engineer.
The course is designed to develop the following Elements of Competency: 1.1 1.2 1.3 1.5 2.1 2.2 2.3 2.4 3.2 3.3

Online LearningStudents are expected to be able to use various sources of online content to apply to their learning.
Basic cource information will be supplied on MyUni.
Learning & Teaching Activities
Learning & Teaching ModesThe course will be delivered via weekly online mini-lectures and on-line quizzes which are to be completed before weekly workshops.
Workshops will be focussed on explanations of problems and solutions to them.
Weekly tutorials will allow students to investigate problems in more detail.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.The course will consist of weekly 2 hour workshops with required pre-viewing of an on-line mini-lecture and participation in an on-line quiz. Tutorials will be held on a weekly basis of up to 1 hour.
As a guide, 12 hours per 3 unit course is expected weekly. 3 unit courses are required to have a minimum workload of 156 hours regardless of the length of the course.

The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
