Zusammenfassung:	The invention relates to a method for extracting anatase coarse powder by using a waste vanadium-titanium denitration catalyst. The method comprises the following steps: A, surface pretreatment; B, pore impurity treatment; C, acid pickling and drying; the invention aims to solve or at least alleviate the problem that the utilization rate of a spent catalyst is low when the spent catalyst is used for extracting anatase coarse powder at present, and provides a method for extracting anatase coarse powder by using a waste vanadium-titanium denitration catalyst. 本发明涉及一种利用废钒钛系脱硝催化剂提取锐钛粗粉的方法，包括以下步骤：A、表面预处理，B、孔道杂质处理，C、酸洗烘干，D、雷蒙超细粉碎。本发明的目的在于解决或至少减轻目前使用失效催化剂提取锐钛粗粉时，失效催化剂的利用率较低的问题，提供一种利用废钒钛系脱硝催化剂提取锐钛粗粉的方法。
