CHEM ENG 7058 - Metallurgical Processes

North Terrace Campus - Semester 2 - 2024

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.

  • 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.
