METHOD FOR PREPARING A FERRIC NITRATE REAGENT FROM A COPPER-REFINING SOLUTION, AND THE USE OF SAID REAGENT IN THE LEACHING AND/OR CURING OF SULPHIDE SPECIES COPPER SUBSTANCES

摘要

The invention relates to a method for preparing a ferric nitrate reagent (Fe(N03)3) from a copper-refining aqueous solution from the hydrometallurgical process for copper minerals containing iron (II) (Fe2 +). The invention also relates to the preparation of the reagent according to the invention for use as a solvent and oxidising agent for copper species minerals in the stages of mineral curing, heap leaching, and/or mineral leaching (ROM) of the hydrometallurgical process for the leaching of copper mineral in a new or existing project.
