Method for removing iron from carbonation leachate

The invention belongs to the technical field of vanadium extraction metallurgy, and particularly relates to a method for removing iron from carbonation leachate. The method for removing iron from the carbonation leachate comprises the following steps: a, adding an iron removal agent into the carbonation leachate, stirring, and carrying out an iron removal reaction; b, after the iron removal reaction is finished, carrying out solid-liquid separation to obtain iron-removed liquid and iron-removed slag; wherein in the step a, the iron removal agent is sodium percarbonate. According to the method, sodium percarbonate is used for removing iron ions in the leachate, and the influence of the iron ions on the quality of a vanadium product is avoided; harmful ions are not introduced in the impurity removal process, so that the cyclic utilization of process water is not influenced. 本发明属于钒的提取冶金技术领域，具体涉及一种碳酸化浸出液除铁的方法。本发明提出的一种碳酸化浸出液除铁的方法，包括以下步骤：a，向碳酸化浸出液加入除铁剂并搅拌，进行除铁反应；b，除铁反应结束后，固液分离，得到除铁后液和除铁渣；其中步骤a中，除铁剂为过碳酸钠。本发明利用过碳酸钠除去
