Description:

This report describes research carried out by the Bureau of Mines to develop new technology for electrorefining metals at much higher current densities than those normally used in commercial practice. Preliminary studies using rotating-ring and cylinder electrodes to increase the mass transport of copper are discussed. Following this work, single- and multichannel cells were developed that utilized a high electrolyte flow in the channels formed by the anode-cathode pairs. Using these cells, copper was successfully refined at current densities in the range of 70 to 300 amp/ft3. The effects of flow rate, electrolyte composition, and grain-refining and leveling agents on the morphology and purity of electrodeposited copper were determined. [Description provided by NIOSH]
