PROCESS FOR PREPARING A FERRIC NITRATE REAGENT FROM COPPER RAFFINATE SOLUTION AND USE OF SUCH REAGENT IN THE LEACHING AND/OR CURING OF COPPER SUBSTANCES.

摘要

This invention relates to a process for preparing a ferric nitrate (Fe(NO3)3) reagent, capable of serving as a solvent and copper species oxidizing agent in the ore curing, heap leaching, and/or run of mine (ROM) leaching of a copper ore hydrometallurgical process located at a brown field or green field, from an aqueous copper raffinate solution from the copper ore hydrometallurgical process of copper ore containing iron (II) (Fe2+), and the reagent prepared pursuant to this process.
