摘要

In order to study calcium leaching behavior for the steelmaking slag, factors that influence the leaching yield have been optimized. The results show that granularity of the slag, liquid to solid ratio (in short for L/S), temperature and reaction time have a significant effect on the leaching yield. The optimal conditions for leaching are determined as follows: 1) the granularity at 75 渭m, L/S at 100, temperature at 60 掳C; 2) the granularity at 75 渭m, L/S at 50, temperature at 40 掳C. Finally, the optimal leaching yield under these conditions is about 15%.
