Extractive Metallurgy I (ENG527)
|Organisational Unit||Engineering and Energy|
|Availability||MURDOCH: S1-internal, S1-external|
|Teaching Timetables||Murdoch S1
|Description||Covers high temperature metallurgical processes such as roasting, smelting and refining. The relevant unit processes are examined through consideration of: thermodynamics and kinetics of interactions which occur among individual phases (i.e. gases, solids, metals, mattes and slag), fluid dynamics, heat-transfer and mass transfer characteristics, different reactors and techniques used to carry out these processes. References to industrial practice for production of materials such as copper, nickel, zinc, lead, gold, aluminium, tin, silicon, iron and steel will be made.|
|Unit Learning Outcomes||On completion of this unit students should be able to:
1. Understand the techniques used in Extractive Metallurgy such as thickening, filtration, centrifuge dewatering and drying.
2. Understand the processes involved in the production of copper, nickel, iron and steel, aluminium, titanium and titanium dioxide, zinc, lead, gold and silicon.
3. Know the methods of tailing disposal and slag cleaning.
4. Understand the environmental issues and how to deal with them including recycling.
5. Understand pyrometallurgical process design and costing.
|Timetabled Learning Activities||Lectures: 3 hours per week.|
|Unit Learning Experiences||The approach to learning in this unit is designed to support students (i) to develop and refine independent learning skills, creative but critical analysis and problem solving skills; (ii) to gain the knowledge on how to access and assess the in-depth professional information and global perspectives via literature and other resources. This will be achieved through lectures focusing on theoretical and practical aspects of Extractive Metallurgy and through self-study exercises that reinforce and extend understanding.|
|Assessment||Three assignments are formative assessments providing feedback to support learning whilst the 2-hour closed book, fully supervised final examination is summative. The assignments come at the end of a defined period of learning, they are valuable to help students recognise areas needing further development for the final exam. Assignment and examination questions are designed to probe knowledge recall as well as critical thinking/problem solving skills. All unit learning outcomes are assessed in the assignment and exam. A literature review gives students the opportunity to gain more in-depth knowledge of a topic of their interest as well as to critically assess the information available in the literature.
Three assignments 30%
Literature review 15%
Final examination 55%
|Prerequisites||Students need to have completed EXM524/ENG524 Metallurgical Unit Operations and ENG565 Mineralogy for Metallurgists prior to enrolling in this unit.|

|Internet Access Requirements||Murdoch units normally include an online component comprising materials, discussions, lecture recordings and assessment activities. All students, regardless of their location or mode of study, need to have access to and be able to use computing devices with browsing capability and a connection to the Internet via Broadband (Cable, ADSL or Mobile) or Wireless. The Internet connection should be readily available and allow large amounts of data to be streamed or downloaded (approximately 100MB per lecture recording). Students also need to be able to enter into online discussions and submit assignments online.|
