研究了不同参数对钢渣在醋酸溶液中钙离子溶出效率的影响.结果表明:钢渣中的钙离子能在醋酸溶液中迅速溶出,其溶出速率随着醋酸体积分数的增大而加快,最大溶出率在83%～85%左右;随着钢渣细度的增大,钢渣在醋酸溶液中钙离子的溶出速率加快;适当提高反应温度可加快钢渣在醋酸溶液中钙离子的溶出速率.

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.
