Mineral Processing Design

This volume is based on the proceedings of the "NATO­ Advanced study Institute on Mineral Processing Design" held in Bursa-Turkey on August 24-31, 1984. The institute was organized by Professor B. Yarar of the Colorado School of Mines, Golden, Colorado, 80401, USA, Professor G. Ozbayoghu and Professor Z. M. Dogan of METU-Ankara, Turkey, who was the director. The purpose of the institute was to provide an international forum on the subject and update the information available. Participants were from Turkey, England, Greece, Spain, Portugal, Belgium, Canada, and the USA. Besides authors contributing to this volume, presentations were also made by Drs. Yarar, Raghavan, Schurger, and Mr. Kelland. Many assistants and colleagues helped. They are gratefully acknowledged. Acknowledgment is also owed to Drs. Ek, de Kuyper, and Tolun. Dr. Gfilhan Ozbayoglu, and Mr. S. Ozbayoglu were particularly helpful in the overall organization and hosting of many international guests. We owe them special thanks. NATO, Scientific Affairs Division, is gratefully acknowledged for the grant which made this activity possible. Z. M. Dogan B.

A procedure for conductiqg mineralogical studies in conjunction with ore dressing was, therefore, developed. The procedure includes characterizing the ore and analysing the mill products.
