Beschreibung
Zusammenfassung:	The invention relates to the technical field of hydrometallurgy, and especially relates to a method for reducing the content of Cu, Cd, Ni, Co and Sb in a zinc hydrometallurgy zinc sulfate solution. The method comprises the following steps: detecting and recording the content of components in the zinc sulfate solution, and adjusting the pH value of the zinc sulfate solution to 2.5-3.5 to make zinc sulfate meet condition requirement in subsequent purifying technologies, improves the removal rate of Cu, Cd, Ni, Co and Sb elements in zinc sulfate and improve the purity of the zinc sulfate solution; adding a cobalt removal agent in the treatment process, stirring, adding zinc powder, stirring, and filtering to simultaneously remove Cu, Cd, Ni, Co and Sb elements from zinc sulfate in order to reduce the content of impurity elements in zinc sulfate, improve the purity of zinc sulfate, complete the purification process at 50-60DEG C and reduce the energy consumption in the purification process.
