Pyrometallurgy (ENG325)

Organisational Unit Engineering and Energy
Credit Points 3
Availability MURDOCH: S1-internal, S1-external
Teaching Timetables Murdoch S1
Description The unit considers principles and applications of unit operations involved in the pyrometallurgical processing of mineral concentrates and ores. This includes gas-solid, solid-liquid, liquid-liquid and liquid-gas reactions relevant to processes such as roasting, smelting and refining. Processes are examined through consideration of the thermodynamics and kinetics of interactions which occur among individual phases, the fluid mechanics, heat-transfer and mass transfer characteristics on the process and equipment side, techniques used to carry out these processes for particular commodities.
Unit Learning Outcomes On successful completion of the unit you should be able to:
1. Apply thermodynamic and kinetic principles to the design and operation of pyrometallurgical processes
2. Make preliminary designs for furnaces to be used in pyrometallurgical processes
3. Discuss the properties of slag systems of industrial importance
4. Discuss the principles behind, and the operational practices of, a wide range of current and prospective pyrometallurgical processes
5. Discuss the environmental impacts of pyrometallurgy and the methods used for amelioration
Timetabled Learning Activities Lectures: 1 x 2 hours per week; Lecture/Workshop: 1 x 2 hours per week; Laboratories: 1 x 2 hours per week.
Unit Learning Experiences This unit mainly consists of lectures and tutorial/workshop sessions covering topics including the importance of pyrometallurgical unit operations, high-temperature thermodynamics, roasting reaction kinetics and specific mass and heat transfer processes and fluid mechanics, modelling and reactor design in the various unit operations relevant to the production of the commodities described above. Lectures will be covering topics such as thermodynamics of melts and solutions, reaction kinetics and mass transfer in fluidised-bed furnaces, design and operation of various pyrometallurgical reactors, graphite electrodes and refractory elements, relevant heat transfer, roasting, slag chemistry and slag cleaning, smelting and converting of non-ferrous metals (Cu and Ni), iron and steel making, aluminium smelting and titanium production, zinc and lead smelting, gold refining and silicon production. Environmental aspects, recycling options, and pyrometallurgical process design and costing will also be discussed. With the help of assignments and laboratory exercises students will gain hands on experience on different types of equipment, analysis of experimental data design capabilities and problem solving exercises.
Assessment Assignments (open book) - 20 %. Use of the materials covered, research and some self-directed study. Each assignment will consist of problem solving exercises. Practical laboratory exercises - 30 %. Students will attend laboratory sessions, submit written laboratory reports and receive feedback through marked reports. Invigilated final examination (closed book theory) - 50 %.
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 EXM302 Advanced Mineral Processing or ENG330 Mineral Processing may not enrol in this unit for credit.

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.
