Study on the Extraction of Calcium from Steel Slag in Acetic Acid

Abstract:

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