Process of Heap Leaching of laterite which comprises providing a Stack based Primary and Secondary leaching, sulfuric acid leaching, base and ferrous ion

摘要

A process for leaching laterite or a Stack of the process includes the steps of: a) providing a primary and a secondary Battery, this Battery comprises a predominantly Primary Sulphide containing nickel and Cobalt or a Mineral type saprolu00edtico,The secondary Battery includes a limonu00edtico predominantly type Nickel ore and cabaltob) the primary stack leaching with sulfuric acid solution to generate a Solution containing ferrous ions; c) use this solution that includes the ferrous ions as lixiviant couple The secondary Battery to Leach, and produce a Mother Solution containing Nickel ion of leachate.COBALT and manganese.
