| description | The present invention relates to a new hydrometallurgical process for recovering nickel from nickel bearing raw materials, such as sulphide flotation concentrates. In general, the process involves the oxidative atmospheric pressure leaching of nickel sulphide concentrates using a sodium chloride/hydrochloric acid based leach media.
La présente invention concerne un nouveau procédé hydrométallurgique de récupération de nickel à partir de matériaux bruts contenant du nickel, tels que des concentrés de flottation de sulfure. En général, le procédé comprend la lixiviation oxydative sous pression atmosphérique de concentrés de sulfure de nickel en utilisant un milieu de lixiviation à base de chlorure de sodium/d'acide chlorhydrique. |
