| description | Systems and methods for basic leaching are provided. In various embodiments, a method is provided comprising leaching a slurry comprising a copper bearing material and an ammonia leach medium, adding copper powder to the slurry, separating the slurry into a pregnant leach solution and solids, and performing a solvent extraction on the pregnant leach solution to produce an loaded aqueous stream.
La présente invention concerne des systèmes et des procédés de lixiviation basique. Selon divers modes de réalisation de l'invention, un procédé fait appel à une lixiviation d'une suspension comprenant un matériau cuprifère et un milieu de lixiviation à base d'ammoniaque, à l'ajout d'une poudre de cuivre à la suspension, à la séparation de la suspension en un jus fort de lixiviation et en solides, et à l'application d'une extraction au solvant du jus fort de lixiviation pour produire un flux aqueux chargé. |
