Review:
The volume represents the proceeding of the Fifth UBC-McGill Biennial International Symposium of Fundamental of Mineral Processing held during the 43rd Annual Conference of Metallurgists of CIM, August 22-25, 2004, Hamilton, Ontario, Canada. Past volumes in this series are:

• Processing of Hydrophobic Minerals and Fine Coal. Editors: J.S. Laskowski and G.W. Poling (1995), ISBN 0-919086-59-4
• Processing of Complex Ores. Editors: J.A. Finch, S.R. Rao and I. Holubec (1997), ISBN 0-919086-74-8
• Polymers in Mineral Processing. Editors J.S. Laskowski (1999(, ISBN 0-919086-89-6
• Interactions in Mineral Processing. Editors: J.S. inch, S.R. Rao and L. Huang (2001), ISBN 1-894475-13-5

According to the editor, materials mined from any deposit represent a highly heterogeneous mixture of solidified crystalline phases consisting of various minerals. Since separation efficiency critically depends on liberation of mineral species, which is accomplished in the most expensive mineral processing unit operations such as crushing and grinding, these topics are frequently discussed at various symposia. However, very fine grinding that may be required to achieve sufficient degree of liberation, produces huge amount of fine particles. Such particles, in spite of being liberated, pose serious problems in both concentration unit operations, and subsequent solid/liquid separation unit operations.

Increasing quantities of fines present a major technological, economic and environmental challenge for resource-based industries. With quite common very fine grinding the efficiency of the particle size enlargement processes will soon become a decisive factor in determining the viability of many mineral processing. The Symposium volume contains 31 papers from 11 countries as follows:

Australia (1 paper), Brazil (1 paper), Chile (1 paper), Iran (1 paper), Mexico (2 papers), Peru (1 paper), Poland (1 paper), Turkey (1 paper), Ukraine (1 paper), USA (6 papers), and Canada (15 papers). They are organized under from headings:

• Introductory lectures (6 papers)
• Hydrophobic aggregation in fine particle beneficiation/flotation (8 papers)Flocculation (9 papers)
• Pelletization and briquetting (8 papers)

The book is very well produced and should be of great value to mineral processing engineers, researches, and students. The editor, J.S. Laskowski is with the University of British Columbia, Vancouver, British Columbia.
