mechanism was confirmed. It was found that particles with high arsenic content were formed in the simulated HRSG, and copper arsenate was liable for the high arsenic content. Pyrite promoted the sulfation of copper, leading to the in-situ decomposition of copper arsenate. In this process, gaseous arsenic was released, and thus the separation of arsenic and copper was realized. Key words: copper......
that As(Ⅲ) is an essential element in purification of the copper electrolyte. Even for no As(Ⅴ) case, the purification performance is still good. Obviously, it can not be explained by the viewpoint of arsenate or arsenato...
