Abstract: The removal of iron in the leaching solution of zinc hydrometallurgy is an important process. Iron ions will be oxidized and reduced on the electrode, resulting in reverse dissolution of cathode zinc, anode corrosion, reduction of current efficiency and increase of energy consumption, which seriously affects the electrowinning process. Iron removal by goethite method has the advantages of less slag, easy filtration and low loss of rare and precious metals. The goethite slag phase produced by precipitation does not contain S element, which can reduce impurity elements from the source and reduce the difficulty of treatment for hot metal pretreatment process in steelmaking. It can be used as ironmaking raw material only by increasing the content of slag iron, so it is the mainstream iron removal method at present. However, the problems of long iron removal time, unstable crystal form and low slag iron content in goethite method lead to poor practical industrial application effect. In view of the above problems, this paper reviews the methods of strengthening and improving the iron removal efficiency of goethite method, such as oxygen pressure hydrothermal method, shear strengthening method, oxidation method, seed induction method, reactor control and neutralization agent optimization method, based on the three formation links of goethite method, such as oxidation, hydrolysis and neutralization. The purpose is to break through the limitations, provide ideas and ideas for the follow-up study of strengthening goethite method, and look forward to the new direction of iron removal by strengthening goethite method.
