Understanding of fundamental phenomena is critical in developing new chemical additives and developing more efficient processes, especially when treating finely disseminated ores that require very fine grinding. Once generated, these fine mineral particles can be subjected to separation by flotation, and finally solid-liquid separation. All these unit operations critically depend on the electrical charge of the solid particles, as well as adsorption of various chemical additives that determine the wettability and particle-particle interaction processes.
This course is structured to discuss interrelated engineering aspects and to show how better understanding of the fundamentals can be utilised to improve industrial results.
Course Objectives
- Introduce basic characteristics of disperse systems
- Equip attendees with understanding of fundamental concepts of surface chemistry
Course Outline
The topics covered will include:
- Introduction to disperse systems
- Basic characteristics of interfaces
- Electrically charged interfaces
- The solid-gas interface
- Adsorption from solutions
- Foams and emulsions
- The relationship between hydrophobicity and floatability
- Presentation, manipulation and analysis of liberation data
- Mineral grade and recovery, calculation of theoretical grade/recovery curves
- Identifying circuit weaknesses
Course Attendees
The course is aimed at mining engineering and chemical engineering graduate students who specialise in mineral processing, as well as manufacturers of mining and mineral processing reagents and mineral processing plant personnel. The material will be presented in an easily understandable manner without the need for mathematical derivations, and without straying too far from topics directly relevant to the fine particle processing related research.
Course Timing and Location
This course is scheduled for 7th - 8th August, 2007.
It will be held at the Julius Kruttschnitt Mineral Research Centre in Brisbane, Australia.

Course Presenters
Professor Janusz Laskowski has been working in the field of surface chemistry and coal processing for many years. He has taught many short courses world-wide on topics such as: Flotation Fundamentals and Applications, Surface Chemistry, Coal Surface Chemistry, Coal Flotation and Fine Coal Utilisation, and Use of Polymers in Mineral Processing.
Janusz obtained all his degrees from the Silesian University of Technology in Poland. He has spent time at many universities including Lomonosov University in Moscow, the Mining Institute of USSR Academy of Sciences in Moscow, Department of Mineral Technology at the Imperial College in London and more recently at the Department of Mining and Mineral Process Engineering at the University of British Columbia in Vancouver. He chaired the International Mineral Processing Congress in 1979 and has published over 200 papers in refereed journals and conference proceedings as well as several books.
Cost
The cost per person to attend this course in Brisbane is AUD2,000 (excl GST).
