Research Group: Sustainable Mineral Processing Laboratory


Job Posting: MASc Student Researcher (materials science and/or electromagetism)

The Sustainable Mineral Processing Laboratory is looking to fill a position for a master’s student to work on tools for high temperature microwave properties measurement.

Preferred start date is ASAP but there is flexibility to begin the role in fall 2018. Ideally the student will have a background in either materials science or electromagnetics. Experience building electronic devices is an asset.

Microwave processing is a technique that has the potential to increase the efficiency of mineral processing, the practice of separating valuable minerals in ore from waste rock. A critical step towards understanding how ores respond to microwaves is to measure the microwave properties (dielectric permittivity, magnetic permeability, and electrical conductivity) of the constituent minerals. Because ores are heated upon exposure to microwaves, the measurements must be conducted at temperatures ranging from ambient to greater than 1000oC. Relatively little work has been done to measure the microwave properties of minerals at high temperature.

Our lab has used the cavity perturbation method to determine the microwave properties of materials at elevated temperature. The instrument used, however, has several shortcomings and is not effective in accurately determining the microwave properties of very high loss materials. The objective of the project is to improve existing measurement tools for high temperature microwave properties measurement, or if this is not feasible, develop a new methodology.

The student will be co-supervised by Professor Hum from ECE. Ideally the student will have a background in either materials science or electromagnetics. The student could be registered in an MASc program in either MSE, ChemE or ECE. Interested students should contact Professor Bobicki by email ASAP at erin.bobicki@utoronto.ca
