2021-10-15  If you are referring to laterite Ni-Co leaching, HPAL is a well established process (Moa Bay, Murrin Murrin, Coral Bay, Ambatovy, etc.). It is essentially an acid digestion, but recovery is increased and residence time shortened through the use of high temperatures (255 ° C -270 ° C) which in turn need high pressure (4,000 kPa – 5, 300 kPa). ). These conditions need the titanium lining ...
