Proceso para producir un reactivo nitrato ferrico para su uso en la etapa de lixiviacion en pilas de minerales de cobre que contienen fierro ii, que comprende concentrar fierro ii en una solucion de refino de cobre y mezclarlo con una solucion acuosa acida de nitrato de sodio; y proceso para la lixiviacion de cobre.

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.
