【Abstract】 A new crystal precipitation process was developed for the separation and recovery of heavy metals from electroplating sludge. The processing parameters including volume of crystal seeds,adding speed of a precipitator and adding speed of the leachate were evaluated according to sequential experimental designs.The optimum separation conditions led to a recovery efficiency of Cu 96.2%,Fe 92.1%,Cr 98.3%.更多还原
