electrowinning copper process

Know More
nbsp 0183 32 Electrowinning process is the method expected to provide the highest purity of final product in a form of copper foil However the heterogeneous metal content of PCBs is challenging for electrowinning as the bioleachate mixture resulting from the leached waste contains several other base metals and components in addition to copper...
Leaching of copper and zinc from the tailings sample
Know More
nbsp 0183 32 This research was aimed to investigate the leaching behavior of zinc and copper from a porcelain stone tailings sample using RSM-CCD modeling The synergetic and individual effects of five main factors including liquid/solid ratio sulfuric acid concentration agitation speed leaching time and temperature were examined on the recoveries of zinc and copper For this purpose two 2F1 models...
