Research of the Wet Recovery Process of a Certain Electroplating Sludge
This paper introduces the wet recovery process of a certain electroplating sludge(containing valuable metals such as copper,nickel and cobalt),which mainly includes:pulping,leaching,copper extraction and electrowinning,iron removal,P204 extraction,P507 extraction of cobalt,C272 extraction of magnesium,MVR evaporation cooling crystallization and fluidized bed drying.It has been proved that the process has high comprehensive recovery rate,and can selectively extract a variety of metal ions from electroplating sludge in four stages(leaching,separation,enrichment and purification),which has good economic value.The final main products are cathode copper,nickel sulfate crystals,cobalt sulfate crystals,etc.
