    • The invention relates to the removal of bivalent copper from copper chloride solution in connection with the hydrometallurgical production of copper. In the copper production process, a copper-bearing raw material is leached with a chloride-bearing solution. The copper chloride solution formed in the leaching, which contains both mono- and bivalent copper, undergoes bivalent copper removal at least in part by precipitation, and the copper(I) chloride solution is conduced to further treatment. Precipitation of the bivalent copper occurs as alkaline copper chloride precipitation. The alkaline copper (II) chloride formed is leached as copper(II) chloride either separately or in connection with raw material leaching, and is used in copper raw material leaching.
    • 本发明涉及从铜的湿法冶金生产中除去氯化铜溶液中的二价铜。 在铜生产过程中,含铜原料用含氯化合物溶液浸出。 含有单价和二价铜的浸出中形成的氯化铜溶液至少部分通过沉淀进行二价铜去除,并且进一步处理氯化铜(I)溶液。 二价铜的析出发生为碱性氯化铜沉淀。 形成的碱性铜(II)氯化物分别或与原料浸出相连,作为氯化铜(II)浸出,用于铜原料浸出。

    • A process is disclosed for separating cuprous chloride from a solution comprising cuprous chloride and one or more of a number of metal impurities, the process comprising crystallizing the cuprous chloride from the solution in the presence of copper as cupric chloride in a concentration of at least about 20 grams per liter. In one embodiment, the process is employed for recovering substantially pure copper from copper sulfide concentrates containing one or more metal impurities, the basic process comprising leaching the copper sulfide concentrates with ferric chloride to produce a leach solution comprising cuprous chloride, cupric chloride, ferrous chloride and the metal impurities, crystallizing a substantial portion of the cuprous chloride from the leach solution in the presence of cupric ion in a concentration of at least about 20 grams per liter in order to produce substantially pure cuprous chloride and a mother liquor, separating the crystallized cuprous chloride from the mother liquor, reducing the crystallized cuprous chloride to substantially pure elemental copper, treating a substantial portion of the mother liquor with oxygen and hydrochloric acid to produce iron oxide, cupric chloride and ferric chloride, and treating the remainder of the mother liquor in order to remove the impurities.

    • An improvement in the process for recovering copper from its sulfide ores or concentrates thereof which comprises treating the ore with cupric chloride and/or ferric chloride to form a copper chloride electrolyte and a residue, electrolytically recovering copper from the electrolyte and further treating the residue with ferric chloride to solubilize substantially all of the copper remaining therein for conversion to copper chloride electrolyte, with ferrous chloride from the electrolyte being regenerated to ferric chloride for leaching the residue, the improvement which comprises conducting the electrolysis without the conversion of any cuprous copper to cupric copper, using a separator between the anolyte and catholyte compartments of the electrolytic cell to prevent passage of ions of copper and iron between the catholyte and anolyte, continuously further treating the residue with regenerated ferric chloride of a concentration to insure there is no cuprous copper in the resulting solution and regenerating ferric chloride from ferrous chloride in the solution free of cuprous chloride by passing the solution through the anolyte compartment of the electrolytic cell as copper is continuously being recovered at the cathode of the cell.
