This study of the simultaneous leaching of copper, gold and uranium from a flotation concentrate is aimed at establishing the conditions that could be applied in a possible heap leach process that would recover all three metals (plus silver, if present) in a single step. The results obtained in this study confirm the results obtained in Part I (Nicol et al., 2024) that enhanced rates for leaching of chalcopyrite from flotation concentrates from two different sources can be obtained in acidic chloride solutions in the presence of chlorate ions. The measurements of the solution potentials during leaching with chlorate are similar to those obtained previously and confirm that chlorine generated by the chlorate-chloride reaction is the active oxidant.

铜、金和铀在氯化物溶液中的联合浸出。II. 精矿浸出测试


这项从浮选精矿中同时浸出铜、金和铀的研究旨在建立可应用于可能的堆浸工艺的条件，该工艺将一步回收所有三种金属（加上银，如果存在）。本研究中获得的结果证实了第一部分（Nicol 等人，2024 年）中获得的结果，即在氯酸根离子存在的情况下，可以在酸性氯化物溶液中获得从两种不同来源的浮选精矿中提高黄铜矿的浸出速率。用氯酸盐浸出过程中的溶液电位测量值与之前获得的相似，并证实氯酸盐-氯化物反应产生的氯是活性氧化剂。
