CHEM ENG 4058 - Metallurgical Processes

North Terrace Campus - Semester 2 - 2022

This course aims to provide the Chemical Engineering students with an understanding of metallurgy techniques that are used in the processing of minerals. The course provides an introduction to the thermodynamics of pyrometallurgical processes including predominance area and Ellingham diagrams and the physical chemistry and transport phenomena involved in a number of pyrometallurgical unit operations including, agglomeration, roasting, smelting, thermal and electrolytic refining. The course covers the processes used in zinc roasting, copper smelting and refining, iron and steel making, lead smelting and refining, nickel smelting, aluminium production, synthetic rutile and titanium production. At the end of this course you should be able to undertake a range of pyro-metallurgical calculations and have an appreciation of the wide range of thermal processes used to extract useful metals and minerals from their ores. 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 activated 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 metallurgical processes in the minerals industry.

    Online Learning
    Students 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 Modes
    The 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.
    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 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.

  • 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.

  • 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鈥檚 disciplinary procedures.
