and utilization of red mud-A review WANG Lu1, HAO Yan-zhong1, HAO Zeng-fa2 (1. College of Science, Hebei University of Science and Technology, Shijiazhuang 050018, China; 2. Hebei Fulinyuan Water Treatment Agent Limited Company, Shijiazhuang 051430, China) Abstract: Red mud is the solid powder waste generated in the process of alumina extraction by bauxite and a strong alkali residue. Mass accumulation......
liquid to solid separation [20-23]. Scorodite can precipitate from acidic solutions that contain arsenic and iron under both hydrothermal and atmospheric conditions. The atmospheric process is more... reactor. The reactor was then heated in a water bath at (100±1) °C for 12 h, and the slurry was stirred continuously at 150 r/min by an impeller. During the first 1 h of heating, the solid As2O3......
been developed, as a solid state process, based on the friction stir welding technique to produce surface metal matrix composites. The surface composites fabricated by FSP using SiC as reinforcements...-graphite mono composite also shows an increased wear resistance due to the formation of a rich layer of lubricant during FSP [9]. This continuous solid graphite-rich layer provides solid lubrication......

be the main passivating species with chalcopyrite leaching in ferric sulfate solution [75]. And the layer will then block the electron transfer at the solid-liquid interface, thus inhibiting... of chalcopyrite was proposed by HIROYOSHI et al [103, 123]. They held that the first step is the reduction of chalcopyrite to chalcocite at low redox potential. Then the newly generated solid species can......
