Abstract After the pretreatment of zinc tail slags by crushing, ball milling and magnetic separation, the iron concentrate with MFe of more than 45% can be obtained. Then the iron concentrate is subjected to secondary ball milling, primary magnetic separation, primary rolling and baking. The iron powder for reduction which all the indexes meet the standard can be obtained. The samples are sent for the reduction test of titanium dioxide powder production, which is approved by the users.
