Zusammenfassung: | A system and process for recovering copper from a copper-containing ore, concentrate, or other copper-bearing material to produce high quality cathode copper from a leach solution without the use of copper solvent/solution extraction techniques or apparatus. A process for recovering copper from a copper-containing ore generally includes the steps of providing a feed stream containing comminuted copper-containing ore, concentrate, or other copper-bearing material (101), leaching the feed stream to yield a copper-containing solution (1030), conditioning the copper-containing solution through one or more physical or chemical conditioning steps, and electro winning copper directly from the copper-containing solution in multiple electro winning stages(1070, 1080), without subjecting the copper-containing solution to solvent/solution extraction prior to electro winning.
La invencion se refiere a un sistema y proceso para recuperar cobre a partir de un mineral, concentrado u otro material que contiene cobre para producir cobre de catodo de alta calidad a partir de una solucion de lixiviacion sin el uso de tecnicas o aparatos de extraccion de disolvente/solucion. Un proceso para la recuperacion de cobre a partir de un mineral que contiene cobre generalmente incluye los pasos de proveer una corriente de alimentacion que contiene mineral (101) que contiene cobre, concentrado que contiene cobre, fragmentado, lixiviacion de la corriente de alimentacion para producir una solucion (1030) que contiene cobre, acondicionamiento de la solucion que contiene cobre a traves de uno mas pasos de acondicionamiento quimico o fisico, y extraccion directa por via electrolitica de cobre a partir de la solucion que contiene cobre en multiples etapas (1070, 7080) de extraccion por via electrolitica, sin someter la solucion que contiene cobre a extraccion de disolvente/solucion antes de la extraccion por via electrolitica. |
