of ammonium sulfate. The results show that sodium sulfate plays a positive role in promoting sulfation roasting of manganese oxide ore and decomposition of ammonium sulfate. When roasting temperature reaches...; 文献标志码:A 文章编号:1672-7207(2018)05-1031-06 Cyclic process for leaching manganese by sulfation roasting of manganese oxide ore ZHANG......
Trans. Nonferrous Met. Soc. China 31(2021) 2153-2164 Formation of arsenic-copper-containing particles and their sulfation decomposition mechanism in copper smelting flue gas Wen-ming YAO1, Xiao-bo... 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......
Preparation of supported nano-copper oxide and its sulfation kinetics YU Qing-chun(郁青春)1, ZHANG Shi-chao(张世超)2, YANG Bin(杨 斌)1, LIU Da-chun(刘大春)1, XU Bao-qiang(徐宝强)1, MA Wen-hui(马文会)1 1... the sulfation of CuO/γ-Al2O3 sorbents. The sulfation tests were performed using gas containing 0.1%-0.9% SO2, 5% O2, 3% H2O steam, and N2 as the balance. Experimental conditions including temperature......
