| Abstract: | Iron removal is a key process in hydrometallurgical processes. The removal of iron impurities can not only improve the quality of the product, but also facilitate the recycling of iron. This article reviews several typical wet iron removal processes in hydrometallurgy, and divides them into leaching (direct leaching, roasting-leaching), precipitation (oxidative precipitation, phosphate precipitation, hydrothermal hydrolysis of hematite, The sulfide precipitation method), extraction method and ion exchange method are analyzed. The principles, processes, advantages and disadvantages of different processes are analyzed, and the development direction of wet iron sinking is proposed. |
