The carbon-in-pulp (CIP) process is now well established in the South African gold industry, with a total of over 1 million metric tons of material being treated each month in six large plants. This tonnage is derived from ground ore, from filtered pulp, from calcine, and from reclaimed sand-tailings dumps. With this new process and the new large plants, those concerned with CIP are experiencing a learning process, since each new plant presents a different set of problems to be overcome. The knowledge and experience gained from these plants is being shared, and will be of benefit in the design and operation of new plants. The CIP process can be subdivided into the following unit operations: prescreening at a fine size, adsorption, acid-washing and elution, reactivation, and electrowinning. Results concerning each of these unit operations, which were obtained from pilot plants and from large-scale CIP plants in South Africa, are presented. The latest developments in each of these areas is summarized. Tables that are included as an appendix contain some information concerning the equipment in these new CIP plants plus operating results from some plants. (AUAB).

The use of activated carbon for the recovery of gold from cyanide solutions or pulps is discussed with respect to the various unit operations of this process, namely, pre-screening, interstage screening, absorption, elution, electrowinning, and reactivation. Particular attention is given to recent developments that have taken place on South African plants which have, for the most part, been associated with the South African philosophy of the treatment of whole ores rather than slimes fractions. The absorption of gold on carbon is examined in some detail, and the factors influencing extraction efficiency are discussed in relation to optimization and control of the absorption section.
