摘要

Scaled copper electrorefining cells were designed,built and computerized to simulate as closely as possible industrial conditions at three Canadian copper refineries.The industrial dimensions of Falconbridge,Kidd Metallurgical Division,were considered while designing scaled cells.Anode width to cellwidth ratio,anode width to cathode width ratio,anodic surface tocathodic surface ratio,as well as electrolyte volume to cathodic surface ratio,as wel as electorlyte volume tocathodic surface ratio,which was about 60 L m~(-2),were consistent with Kidd's industrial ratios.However,thecell design also allowed simulation of INCO's Coper Cliff Copper Refinery (CCCR) or Noranda's Canadian Copper Refinery (CCR).Electrorefining cells were 135.0 cm deep by 14.7 cm wide.Electrolyte flow rate was paralledl to the electrodes.Electrolyte was circulated from thelower part of the electrorefining cells to the top where there was an overflow going to the electrowinning circuit.The equipment was computer controlled using Labview software.Experients were conducted using this scaled electrorefining setpup to evaluate the effect of various ratios and concentrations of additives on nodulation during copper electrorefining under highcurrent densities.Cathodic polarization curves,SEM micrographs,porosity analyses and copper grain analyses were used to characterize the cathodes produced.
