Research Status of the Effect of Typical Impurity Minerals and Ions on Chalcopyrite Leaching
-
摘要:
黄铜矿常与黄铁矿、石英、碳酸盐类及硅酸盐类等杂质矿物共生，而这些矿物的存在会对黄铜矿的浸出产生一定影响。此外，黄铜矿浸出时常需加入一些氧化剂来促进其溶解，而额外加入的氧化剂产生的离子以及杂质矿物自身溶解产生的离子也会影响其浸出效率。因此，本文综述了近年来典型杂质矿物及溶液中离子对黄铜矿浸出影响的相关研究，旨在为实现高效完全黄铜矿浸出提供理论支撑和科学依据。
Abstract:Chalcopyrite is often associated with some impurity minerals such as pyrite, quartz, carbonateand silicate minerals, and the presence of these minerals will affect the leaching of chalcopyrite. Additionally, to promote the dissolution of chalcopyrite, some oxidants often need to be added in its leaching process, which generates manyunavoidable ions. Therefore, involving the ions produced from the dissolution of impurity minerals will affect the leaching efficiency of chalcopyrite.In this paper, the effect of the typical impurity minerals and ions on chalcopyrite dissolution was reviewed for providinga theoretical foundation for the high-efficiency and complete CuFeS2 leaching.
