GOLD FIELDS

The CIL circuit consists of two trains of eight tanks in series fed from a common leach tank. The loaded carbon passes into a 15 t acid wash column. The gold is recovered from the loaded carbon in two 15 t elution circuits. Gold is recovered from solution by electrowinning. The gold is smelted in the CIL smelt house in an induction furnace.
