Leaching takes place with ammonia ammonium sulfate liquor in a series of tanks where air is sparged. The leaching reaction is very fast, and controlled by the rate of oxygen transfer. Ammonia gas is recovered from the off-gas and collected as an aqueous solution. The PLS contains about 30 g/L copper as Cu (NH 3) 4 ++.
