Mineral Processing II (ENG329)
|Organisational Unit||Engineering and Energy|
|Description||This unit provides students with a sound basis in the concentration of minerals according to their surface characteristics, including the unit operations froth flotation, agglomeration and flocculation. It includes a substantial section on the dewatering of concentrates and tailings, involving flocculation, thickening, filtration, centrifuging, drying and tailings disposal unit operations. It is designed to develop a solid understanding of both the theoretical and practical aspects of the subject matter which chemical and metallurgical engineers need to apply in the minerals resources industry.|
|Timetabled Learning Activities||Lectures: 1 x 3 hours per week; laboratories: 1 x 3 hours per week|
|Unit Learning Experiences||This unit mainly consists of lectures and tutorial/workshop and laboratory sessions.
Lectures will cover basic principles of the unit operations relevant to froth flotation, dewatering technology and tailings disposal as applied to mineral processing. On the flotation side this will include topics such as fundamentals of froth flotation, flotation theory, electrokinetics, kinetics, flotation reagents and reagents handling, flotation machines and control, flotation circuits for sulphide and non-sulfide ores agglomeration and other methods. On the dewatering side, this will include topics such as dewatering theory and flocculation, thickening and thickening process design and equipment, filtration theory and machines, centrifuge dewatering and thermal drying, and tailings disposal and other dewatering methods.
|Other Learning Experiences||1-2 field trips to local mine sites. Students are required to write a brief report on their site visits.|
|Assessment||Practical Exercises - 30%. Student will write laboratory reports and receive feedback through marked reports.
Assignment - 10%. Use of the materials covered, research and some self-directed study. Each assignment will include problem solving exercises.
Class tests - 10%. Based on lecture presentation slides and practice problems and solutions provided to students .
Computer assisted design project - 10%. Students will use CAPE tool such as SysCAD to design a flotation unit operation.
Closed Book Theory Examination - 40%.
|Prerequisites||ENG202 Engineering Thermodynamics, ENG255 Chemical Process Kinetics, ENG201 Fluid Mechanics, ENG203 Heat and Mass Transfer and ENG205 Process Mineralogy.|
|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.|
