Hydrometallurgy (ENG326)

Organisational Unit Engineering and Energy
Credit Points 3
Availability MURDOCH: S2-internal, S2-external
Teaching Timetables Murdoch S2
Description This unit considers the principles and applications of pre-treatment, leaching, solution purification and metal recovery to the hydrometallurgical processing routes for metals/alloys, ores, concentrates and recycled materials. It also considers practical industrial processes, and discusses overall processes for the recovery of gold, copper, nickel, uranium etc. and value added commodities related to the Australian and global mineral and metallurgical industry.
Unit Learning Outcomes 1. Identify and communicate the unit operations involved in hydrometallurgical processes
2. Apply mineralogical, physico-chemical, chemical engineering and mathematical modelling aspects related to hydrometallurgical unit operations.
3. Solve problems related to thermodynamic, kinetic and chemical/electrochemical aspects of the reactions involved in hydrometallurgical unit operations including pre-treatment.
4. Analyse and apply small scale laboratory experiments relevant to hydrometallurgical processes, analyse the results and apply them in design.
5. Develop and design hydrometallurgical flow sheets suitable for different feed material.
Timetabled Learning Activities Lectures/workshops: 1 x 3 hours per week; laboratories; 1 x 3 hours per week
Unit Learning Experiences This unit mainly consists of lectures and workshop sessions covering topics including the importance of thermodynamics, kinetics, electrochemical aspects, modelling and reactor design in various unit operations described above.
Lectures will be covering the options such as in-situ / heap / tank / atmospheric / pressure leaching, factors affecting leaching efficiency, precipitation for purification of leach liquors or the recovery of value added products and removal of impurities. Lectures in solvent extraction and ion exchange will cover reagent and resin types, extraction, stripping, adsorption and elution isotherms, kinetics, mass balance and design of counter-current circuits. Chemical and electrochemical methods of recovery of pure metals will also be discussed.
With the help of case studies and laboratory exercises students will gain experience on different types of equipment, analysis of experimental data, design capabilities, problem solving abilities and individual/group learning exercises.
The laboratory reports, PowerPoint presentation and critical review of a chosen research article and a PowerPoint presentation will enhance the communication skills.
Other Learning Experiences Students may participate in a plant visit during the semester to appreciate the scale of industrial operations and meet with the managers and discuss their potential vacation employment opportunities. They will also attend various research seminars presented by graduate students and invited industry speakers.
Assessment Written case Study (20%): Use of the materials covered, research and some self-directed study. The case studies will assess the application of knowledge and skills.
Practice/design (30%): Practical exercises and computer assisted design relevant to hydrometallurgical unit operations. Students will write laboratory reports and design(s) and receive feedback through marked reports.
Practice Poster or PowerPoint presentation (10%): Students will be assigned research articles to write critical analyses (2-3 pages ) and prepare a poster or slides for a10 minute PowerPoint presentation.
Written Examination (40%): Closed book theory and problem solving examination.
Prerequisites ENG202 Engineering Thermodynamics, ENG255 Chemical Process Kinetics, ENG205 Process Mineralogy, and either/both ENG201 Fluid Mechanics and ENG203 Heat and Mass Transfer or ENG224 Principles of Unit Operations.
Exclusions Students who have successfully completed the unit EXM357 Extractive Metallurgy may not enrol in this unit for credit.
Notes Unit Study Guide provided. Internet access required and compulsory 3-day on-campus laboratory session or a suitable alternative arrangement. Due to the nature of offering this unit students are recommended to seek confirmation of the exact attendance dates and requirements from the Unit Coordinator closer to the commencement date of each teaching period.

Internet Access RequirementsMurdoch 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.
