Abstract The gradual decrease of global copper resources is among the most urgent challenges for the mining industry. Sustainable utilization of copper sulphide flotation concentrate from iron oxide copper gold (IOCG) deposits is often constrained by the impurity elements (e.g. U, Th and F) and high levels of gangue minerals (e.g. iron oxide/hematite, U-bearing minerals and fluorite). Herein, a spontaneous oxidative H2SO4 leach process (

自氧化硫酸浸出工艺对铜浮选精矿的选择性除杂和铜升级

摘要 全球铜资源的逐渐减少是矿业面临的最紧迫挑战之一。来自氧化铁铜金 (IOCG) 矿床的硫化铜浮选精矿的可持续利用通常受到杂质元素（例如 U、Th 和 F）和高含量脉石矿物（例如氧化铁/赤铁矿、含 U 矿物和萤石的限制） ）。在此，自发氧化 H2SO4 浸出过程（
