plant and/or full-scale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine. In this case, the most appropriate approach is to,CIP AND CIL CIRCUIT MODELLING - SGS,reducing soluble gold losses from a CIP or CIL plant. We can help you accomplish this by: • Increasing the number of adsorption stages. • Increasing the amount of carbon in each stage. • Reducing gold loading by moving carbon to elution and regeneration more rapidly. • Improving the quality of the recycled carbon by improving acid washing, elution and regeneration efficiency.
