SHORT COURSE

FROTHERS AND THEIR USE IN FLOTATION

Thursday, August 9, 2001, 9 a.m. to 5 p.m.

Auditorium of Polk Community College, Lakeland Campus

Sponsored by: Florida Institute of Phosphate Research

Objective:

A froth, as the term “froth flotation” indicates, is an inseparable part of the flotation system. Frothers are used to stabilize the froth, but they are also needed to enhance generation of fine bubbles and to aid particle-to-bubble attachment. A poor understanding of the sub-processes in which frothers participate contributes significantly to the incomplete understanding of the flotation process.

The aim of this one-day school is to review chemistry, physico-chemical properties and mode of action fundamentals of flotation frothers, and frother applications. The course will discuss the role the frothers play in the liquid and froth phases of the flotation system. One of the course objectives is to identify of what we know (including most recent research results), of what we think we know, and to identify possible engineering implications.

The course is designed for engineers working in mineral and particulate processing industries, technical personnel working for reagent suppliers, and scientists researching the field of flotation science and engineering. It is intended to provide the course participants with an understanding of the principles of flotation reagent selection and with the better ways of utilizing such reagents.

The Speaker: 

Professor Janusz Laskowski of the University of British Columbia, Canada.

Dr. Laskowski obtained all his degrees from the Silesian University of Technology in Poland.

He conducted research in surface chemistry and minerals processing at various institutions, such as the Lomonosov University of Russia, Mining Institute of USSR Academy of Sciences in Moscow, Imperial College in London, University of Chile, University of Berkeley, the Ecole Nationale Superieure de Geologie, France, and the University of Cape Town. Since 1982 Dr. Laskowski has been a professor of mineral processing at the Department of Mining and Mineral Process Engineering, University of British Columbia, Vancouver. 

In 1984, he founded the Coal Preparation international journal and has been its editor-in-chief since. Dr. Laskowski has published almost 200 papers in refereed journals and conference proceedings and recently edited four books: “Frothing in Flotation”, “Colloid Chemistry in Mineral Processing”, “Frothing in Flotation II”, and “Apparent and Microscopic Contact Angles”.
