本文报导美国矿业局为改进电解精炼过程进行的工业生产规模研究结果。在新改进的电解精炼过程中,采用了较简便的方法除去钴和铁。因为这种新改进可以把钴、铁完全与镍分离,所以能生产出一种一比般电解镍更纯的镍金属。流程试验研究表明:在用不含铜的氧化矿熔炼得的含镍为25～70%的高品位镍铁生产纯 This article reports the results of a study conducted by the U.S. Bureau of Mines to improve the scale of industrial production in the electrolytic refining process. In the newly improved electrolytic refining process, a simpler method is used to remove cobalt and iron. Because of this new improvement, cobalt and iron can be completely separated from nickel, thus producing a purer nickel metal than electrolytic nickel. Flow test studies have shown that in the high-grade nickel and iron containing 25 to 70% nickel melted with copper-free oxide minerals, pure
