Effects of different factors on the leaching of calcium from steel slag with acetic acid were investigated.The results show that calcium can be leached rapidly from steel slag in acetic acid solution,the leaching rate can be accelerated with the increase of acetic acid concentration of the solution and the largest leaching ratio is about 83%~85%.The leaching rate can also be accelerated with the increase of the fineness of steel slag or reaction temperature.
