摘要

A process for leaching valuable Metal from oxidized Materials,Such as lateritic Nickel ore, which comprises the step of leaching the Ore leaching with a Salt comprising a cationic and hydrochloric acid.You can add additional Oxidant or metal chloride as the resulting from the leaching operation.In One embodiment, the process includes the Recovery of valuable Metal from material, comprising the steps of leaching the Ore leaching with,Separate the rich in valuable metal leaching from ore in a solid / liquid Separation, oxidation and Neutralize the rich in valuable metal leaching so obtainedAnd separate a Magnesium chloride solution from leaking so obtained in a Second solid / liquid separation.In another embodiment, the solution is regenerated from the Dissolution of magnesium chloride solution.In an additional Modality, the regeneration of the Dissolution Solution includes the step of producing Magnesium oxide from Magnesium chloride solution.
