BOOK REVIEWS Mineral Comminution Circuits Their Operation and Optimisation T.J. Napier-Munn, S. Morrell, R.D. Morrison and T. Kojovic Julius Kruttschnitt Mineral Research Centre, Queensland, Australia. 1996. Price Aus$85. 413 pps. ISBN 0 646 28861 X This book is No.2 in the JKMRC monograph series in mining and mineral processing and can be obtained from the publishers, an order form and brochure can be mailed on request. They have also recently published another book entitled "Open Pit Blast Design: Analysis and Optimisation" which is available at the same list price. This book is a must for anyone wishing to get the most from a crushing or grinding circuit. Anyone seeking a deeper understanding of the principles and factors affecting the unit processes involved in crushing and grinding circuits will find this text of immense use. If you have read the earlier work of Professor Alban Lynch, then you will need no convincing of the need for an up-dated version of that excellent text. Significant advances have been made over the past 20 years to make the writing of this book necessary. The first chapter introduces the subject, the equipment and the use of simulation, and concludes with some very useful advice on how to make the best use of the book. Chapter 2 gives an overview of models of comminution processes which is a very helpful introduction to the concepts for someone who is unfamiliar with this topic area. The third chapter addresses the topic of mineral liberation, and the approach used at the JKMRC in particular, and chapter 4 follows with a detailed description of the methods used to establish the materialspecific breakage function. Chapter 5 is a very useful addition, giving practical guidance on how to survey a comminution circuit. This is an area which is all too often overlooked and it is pleasing to see it given the importance that it deserves. The bulk of the text is covered in chapters 6-12, which take the different unit operations in turn and describes the equipment, principles of operation and their mathematical models. Each chapter stands alone and so the reader with an interest in a specific unit operation can go directly to the relevant chapter without reading the whole book. The final chapter deals with the topic of circuit optimisation, with several case studies to illustrate the techniques being described. This is an excellent text and should prove invaluable to anyone working in the field of crushing and grinding. Inevitably the models that are described in most detail within the book are the ones that have been developed at the JKMRC, but this does not detract from the usefulness of this text. The principles and mechanisms described are not JKMRC specific and thus the book should be useful to all in this field, not just those who are familiar with JKSimMet. I feel sure that this will soon become a common sight on the shelves of practising engineers.
