PREFACE This publication, which supersedes Report M85, is a compilation of all the publications of the National Institute for Metallurgy (NIM) and its successor, the Council for Mineral Technology (Mintek), having an unrestricted distribution list. The NIM reports end with Report 213SD, and the Mintek reports start with Report Ml. The present publication includes all the unrestricted reports and the patents issued and registered by these organizations from 1966 to 31st March, 1984, the confidential reports that were declassified during that period, all the papers published during that period where one of the authors was, or is, a member of staff, znd the other publications that do not fall into the categories already mentioned. The total number of unrestricted reports included is 895, the patents amount to 45, the number of papers published is 508, and the other publications amount to 7. For ease of reference, all the reports, papers, patents, technical bulletins, and special publications listed here have been classified as far as possible into various research topics. A list of these topics is given in Section 6, together with the .lumbers of the pages on which the publications are classified according to topic. This publication also gi'es details of the periodicals issued by Mintek and concludes with a list of miscellaneous publications, which are additional to those mentioned above. These include current brochures. CONTENTS PREFACE 1. LIST OF UNRESTRICTED REPORTS 1 2. PAPERS BY STAFF 42 3. PATENTS 77 4. SPECIAL PUBLICATIONS 81 5. TECHNICAL BULLETINS 81 6.
