CHEM ENG 4058 - Hydrometallurgy & Electrometallurgy

North Terrace Campus - Semester 2 - 2018

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.

  • Learning & Teaching Activities
    Learning & Teaching Modes
    The course will be delivered via weekly lectures supported by in class and non contact problem based learning.

    Lectures will be delivered in a collaborative environment and it is expected that the students participate in class discussion on all topics.
    Workload

    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 lectures with required pre-reading up to 1 hour. Tutorials will be held on a weekly basis of up to 1 hour. The student will be expected to undertake further research and learning outside of contact hours.

  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    The end of year exam will be closed book and of 2 hours duration. The exam will be problem based covering all of the material learnt and discussed during lectures.

    Fortnightly tutorials will be based on material learnt in the previous weeks of the course. Tutorials will be problem based and will be undertaken in groups. Self and peer assessment may apply to marking.

    Attendance at each lecture will be taken 10 minutes after the lecture commences. Participation will be marked on the level of participation, applicabliility of issues raised and thought provocativeness of the discussion.

  • Student Feedback

    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.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    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.
