6. CLASSIFICATION OF RESEARCH TOPICS
In Sections A and B, the research topics at Mintek are classified according to metal or mineral. Thus, Section A, entitled 'Important Metals and Minerals', has subsections for the main base metals (cadmium, cobalt, copper, lead, nickel, and z;ic); ferro-alloys, iron, and steel; gold and silver; platinum-group metals; and uranium. Section B. ^nt fled 'Other Metals, Elements, and Minerals', includes the commodities that are not covered by Section A. Section C includes processes, equipment, reagents, and techniques that cannot be classified under a particular commodity. Section D, entitled 'Properties of Metals and Special Process ng', relates to physical metallurgy, and the last section (E) includes matters related to the wuik of Mintek that cannot be classified under any of the other headings. The page numbers on which the publications are arranged according to topic are given on the right-hand side of the following list. Where no page number is given for a topic, it means that no publications have been issued under that topic.

7. CLASSIFICATION OF PUBLICATIONS ACCORDING TO RESEARCH TOPIC
The publications are listed under topic in the following order: reports, papers, patents, special publications, and technical bulletins. Because the topics are very closely allied, many publications couH have been listed under more than one topic. A reader in search of publications on a particular subject is therefore advised to consult all the topics relevant to his subject. Copies of most of the reports and special publications are obtainable from Mintek, Private Bag X3015, Randburg, 2125 South Africa. For those which are out of print, photocopies can be supplied at a nominal charge. The papers and patents are not available from Mintek: the papers can be consulted in the journals or books in which they were published; copies of the South African patents are obtainable from The Registrar of Patents, Trade Marks and Designs, Private Bag X400, Pretoria 0001, South Africa, and copies of the other patents from the Patent Office, 25 Southampton Buildings, London WC2A 1AY, England.
