CHEM ENG 4059 - Pyrometallurgy

North Terrace Campus - Semester 1 - 2014

This course aims to provide Chemical Engineering students (majoring in Minerals Processing) with an understanding of the principles governing a range of thermal processes applied to extract metals from mineral ores produced from Australian and overseas mines. The course provides an introduction to fuels and combustion processes, furnace heat transfer (including the concept of available heat), thermodynamics of solid-liquid and solid-solid-solid mixtures, Ellingham diagrams, phase diagrams and unit operations including calcination, roasting, smelting, retorting, thermal refining, process control and safety. The course covers the processes used in copper smelting and refining, iron and steel making, lead, nickel smelting and Ferro-nickel production, synthetic rutile, titanium and zinc. At the end of this course you should be able to undertake a range of combustion and pyro-metallurgical calculations and have an appreciation of the wide range of thermal processes used to extract useful metals and minerals from their ores.

  • 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’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.
