The SGS CIP/CIL modelling package maximizes gold extraction efficiency by 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.
