  • Solid-Liquid-Solid Hydrometallurgical Process Optimized to Increase the Solubilization of Metals from Ores and/or Concentrates in Acid-Chloride Medium
    Publication number: 20220356544
    Abstract: The present invention describes a Solid-Liquid-Solid hydrometallurgical process, optimized and independent of redox potential, to increase the solubilization of metals from ores and/or concentrates with a granulometry of less than 40 mm, by means of an initial stage called “Activation”; a second stage called “Dry autocatalytic transformation”; a third stage called “Washing and re-wetting”; and where the stages of dry autocatalytic transformation and washing and re-wetting, can be repeated in an alternating and repeated way.
