【摘要】 研究了三水铝石矿机械活化球磨溶出的最佳工艺条件:装球量30%;钢弹转速100 r/min;料球比1.2∶1;球磨钢球的大小采用混合球;给矿粒度为-0.71 mm;溶出时间为40 min。研究了三水铝石矿在不同温度、溶出时间的溶出率,动力学分析表明:150℃溶出条件下三水铝石机械活化球磨溶出是化学反应控制,而非球磨溶出为扩散控制。更多还原

【Abstract】 The optimal process conditions for the mechanical activation ball mill leaching of gibbsite are: the ball load is 30%,the rotating speed of steel bomb is 100 r / min; the grinded material to grinding media ratio is 1. 2∶1; the steel ball of ball mill is hybrid ball;the particle size of feeding ore is- 0. 71mm; the leaching time is 40 min. The leaching rate of gibbsite with the different temperature,leaching time is studied,and the dynamics analysis shows: The mechanical activation ball mill leaching of gibbsite is the chemical reaction control under 150℃,but not the diffusion controlling of ball mill leaching.更多还原
