Vanadium titano-magnetite smelting slag activation method
The invention discloses a vanadium titano-magnetite smelting slag activation method, and belongs to the technical field of smelting slag activation. The vanadium titano-magnetite smelting slag is crushed to obtain vanadium titano-magnetite smelting slag powder, the vanadium titano-magnetite smelting slag powder is dried under a constant temperature condition to remove all adsorbed moisture in the material, and the vanadium titano-magnetite smelting slag powder is uniformly mixed with a synergist and then put into a microwave reactor for microwave treatment; and the powder and a grinding aid into a planetary ball mill, and ball milling is carried out under the protection of inert gas or in 10% air or air atmosphere. According to the method, the hydration activity of the surface of the powder is greatly excited, the specific surface area is greatly increased, the powder subjected to microwave treatment is further subjected to ball milling under the effect of the liquid grinding aid, static electricity on the surface of the powder with the high specific surface area can be effectively reduced, powder aggregation is prevented, and therefore, the vanadium titano-magnetite smelting slag micro-powder with high activity and high dispersity is obtained under lower power consumption, and high-quality treatment of the vanadium titano-magnetite smelting slag is realized.
本发明公开了一种钒钛磁铁矿冶炼渣活化方法，属于冶炼渣活化技术领域，将钒钛磁铁矿冶炼渣粉碎，得到钒钛磁铁矿冶炼渣粉，在恒温条件下烘干，除去物料中全部吸附水分，与增效剂混合均匀后放到微波反应器中，进行微波处理；与助磨剂一起加入到行星式球磨机中，在惰性气体保护或者10％空气或者空气气氛中进行球磨，即可。本发明极大地激发了粉体表面的水化活性，比表面积大幅度提升，经微波处理后的粉体再在液体助磨剂作用下进一步球磨，其能有效地消减高比面积粉体表面的静电，防止粉体聚集，从而在较低的电耗下获得高活性、高分散性的钒钛磁铁矿冶炼渣微粉，实现了钒钛磁铁矿冶炼渣高质化处理。
