Reactive Oxygen Species in Novel Hydrometallurgical Processes

Novel hydrometallurgical processes based on the reactive oxygen species (ROS) for high-efficiency treatment of refractory amphoteric metal-containing mineral resources have been developed. Due to the strong oxidizing capacity, ROS-rich sub-molten salt media significantly decrease the reaction condition and increase the extraction ratio in comparison of traditional methods. New concept and insight of ROS intensification and ROS electrochemical modulation has been proposed recently.
