PROCESSO PARA RECUPERAR NÍQUEL OU COBALTO

摘要

In step b (leaching step), a slurry ore 104 is leached with sulfuric acid 105 to obtain a sulfuric acid leachate 108 containing nickel and cobalt and a leaching residue 109. Here, the leaching residue 109 contains Natrojarosite generated by a reaction of iron leached from the slurry ore 104 with sulfuric acid 105 and a sodium salt 106.
