In the primary nickel flowsheet, the ore was treated directly by roasting and then ammonia leaching . A steam strip served to reduce the ammonia concentration to a value suitable for extraction of the nickel ammonia complex (Fig. 13). Co (II) present in the liquor was oxidised to Co (III) to avoid its co-extraction .
