Summary:The invention relates to the field of chemical engineering and environmental protection, in particular to a method for selectively leaching metal in vanadium-titanium slag based on a mechanochemical method, which comprises the following steps: mixing vanadium-titanium slag particles with a chemical agent and a grinding aid, and then carrying out ball milling; the particle size of the ball-milled material is smaller than or equal to 0.2 mm; and leaching the ball-milled material by using a leaching solution. According to the method, the metals in the vanadium-titanium slag can be leached under the conditions of normal temperature and normal pressure and mild operation conditions, and corresponding metals can be selectively leached according to different metal components in the vanadium-titanium slag. 本发明涉及化工与环保领域,具体涉及一种基于机械化学法钒钛渣中金属选择性浸出的方法,包括将钒钛渣颗粒与化学药剂及助磨剂混合后进行球磨;使球磨后的物料粒径小于或等于0.2mm;将球磨后的物料用浸出液进行浸出。本发明方法能在常温常压条件且操作条件温和的环境下进行钒钛渣中金属的浸出,还可以根据钒钛渣中金属组分的不同选择浸出相应金属。
