Oxidized copper phase precipitation in ammoniacal

1982-1-1  The same features are observed after an ammoniacal leach of 60, 120 and 150 min. However, as shown in Fig. 3, the time necessary to dissolve the oxidized copper phase increases when the duration of the ammoniacal leach has been increased. This is probably due to a better ordering of the oxidized copper phase lattice with time.
