The Latest Development and Application of Selenium Extraction Process

The main raw materials of Se extraction are introduced.The latest development and application of selenium extraction both at home and abroad is elaborated.The characteristics of Se pyrometallurgy and hydrometallurgy are analyzed.Compared with pyrometallurgy,Se hydrometallurgy has the advantages of low energy consumption,clean and environmental-friendly production and low operating cost.Therefore,hydrometallurgical process will gradually replace the pyrometallurgical process as the dominant process for Se extraction.
