前言从德卢思辉长岩的铜-镍混合精矿中选择性浸出镍的电化学问题,在有关文献中已作过报导。同时也已指出,在较高的阳极电流密度下,随着正电位值的提高,从精矿中溶解的铜数量也就增加。本文讨论了在硫酸介质中于一定的电流密度下,从上述精矿中电化学溶解铜和镍的某些结果。 Introduction The electrochemical problem of selective leaching of nickel from copper-nickel mixed concentrates from the Duluth-Gabbro has been reported in the literature. It has also been pointed out that at higher anode current densities, as the positive potential increases, the amount of copper dissolved from the concentrate increases. This article discusses some of the results of electrochemically dissolving copper and nickel from the above concentrates at a certain current density in a sulfuric acid medium.
