Abstract
La presente invención se refiere a un procedimiento químico reductivo autocatalítico con interacción sólido-sólido en condiciones de sobre-saturación de sales, mediante el fenómeno de eflorescencia para solubilizar un metal de cobre, desde un mineral metalogénicamente primario o concentrado calcopirítico que lo contiene. Este procedimiento está compuesto por 2 etapas, denominadas "Etapa de Activación Reductiva" y "Etapa de Transformación Reductiva Autocatalítica en Seco" o de Eflorescencia, las cuales pueden ser repetidas las veces que sean necesarias para maximizar la extracción de cobre o metal base de interés. La invención también puede ser aplicada a metales base sulfurados tales como níquel, zinc, cobalto, plomo, molibdeno, entre otros, independientemente de impurezas habituales de los minerales sulfurados, como ocurre con la presencia de arsénico.The present invention refers to an autocatalytic reductive chemical process with solid-solid interaction under conditions of supersaturation of salts, through the phenomenon of efflorescence to solubilize a copper metal, from a metallogenic primary mineral or chalcopyrite concentrate that contains it. This procedure is composed of 2 stages, called "Reductive Activation Stage" and "Dry Autocatalytic Reductive Transformation Stage" or Efflorescence, which can be repeated as many times as necessary to maximize the extraction of copper or base metal of interest. . The invention can also be applied to sulfurized base metals such as nickel, zinc, cobalt, lead, molybdenum, among others, independently of the usual impurities of sulfurized minerals, such as the presence of arsenic.
