摘要
Abstract
Vanadium tailing ultra-grinding experimental research was carried out in an agitating mill.Sodium pyrophosphate was found to be the most effective aid in four kinds of grinding aids.The results show that the best parameters of ultra-grinding of vanadium tailing in agitating mill which determine throught particle size distribution,surface potential and surface adsorption properties and morphology are as follows:the sodium pyrophosphate mass ratio of 1.8％,pulp mass concentration of 1 g/mL and grinding 30 min.The product obtained D50=7.85 μm、D90=19.78 μm which reduce 2.97,8.47 μm respectively compared with the blank and grinding time shorten at least 10 min in addition.The surface potential is increased,the adhesion of fine particles on the surface and the viscosity of pulp is reduced with the sodium pyrophosphate adsorbing on the surface of vanadium tailing particle,which improve the fine grinding of vanadium tailing efficiency in the end.关键词
