    • A process is disclosed for separating cuprous chloride from a solution comprising cuprous chloride and at least one metal chloride compatible with the solubility of cuprous chloride, the process comprising crystallizing the cuprous chloride from the solution in the presence of cupric chloride in an amount such that the cupric chloride to compatible metal chloride mole ratio is at least about 0.1. In one embodiment, the process is employed for recovering substantially pure copper from copper sulfide concentrates, generally 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 order to produce cuprous chloride crystals 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.
    • 公开了一种从包含氯化亚铜和至少一种与氯化亚铜的溶解度相容的金属氯化物的溶液中分离氯化亚铜的方法,该方法包括在氯化铜存在下从溶液中结晶氯化亚铜,其量使得 氯化铜与相容金属氯化物的摩尔比至少约为0.1。 在一个实施方案中,该方法用于从通常含有一种或多种金属杂质的硫化铜浓缩物中回收基本上纯的铜,其基本方法包括将硫化铜精矿与氯化铁浸出以产生包含氯化亚铜,氯化铜的浸出溶液 ,氯化亚铁和金属杂质,从浸出溶液中结晶大部分氯化亚铜,以产生氯化亚铜晶体和母液,将结晶的氯化亚铜与母液分离,将结晶的氯化亚铜还原成基本上纯的 元素铜,用氧和盐酸处理大部分母液以产生氧化铁,氯化铜和氯化铁,并处理剩余的母液以除去杂质。

    • A process for forming a metal chloride of a metal or its compound comprising forming a liquid fused salt bath mixture of at least two metal chlorides with one of the chlorides being selected from the group consisting of ferric chloride, ferrous chloride, cupric chloride and cuprous chloride, and introducing the metal or compound into the liquid fused salt bath in the presence of a chlorine source to form the metal chloride and elemental sulfur, and recovering the formed chloride from the liquid fused salt bath mixture. Chlorine gas or sulfur chloride may be introduced into the bath as an additional source of chlorine for reaction with the metal and for the generation of a portion of the ferrous chloride or cuprous chloride into ferric chloride or cupric chloride.
    • 一种形成金属或其化合物的金属氯化物的方法,包括形成至少两种金属氯化物的液体熔融盐浴混合物,其中一种氯化物选自氯化铁,氯化亚铁,氯化铜和氯化亚铜 ,并在氯源的存在下将金属或化合物引入液体熔融盐浴中以形成金属氯化物和元素硫,并从液体熔融盐浴混合物中回收形成的氯化物。 可以将氯气或氯化硫作为额外的氯源引入浴中,以与金属反应并将一部分氯化亚铁或氯化亚铜生成氯化铁或氯化铜。
