Galena Lead Oxidation

Further as most flotation pulps contain less than 10 galena oxidation products the data indicates that oxidised lead extraction should be very efficient. Hence at these lower levels it would be expected that greater than 92 of galena oxidation products would be recovered into a 0.1 M EDTA solution within 5 min leaching .
