nickel &cobalt electrowinningmost of the electrowinning tests were conducted in a 4.5liter acrylic cell, 15 x 20 x 16.5 cm, with a single cathode, 15 x 16 cm, of either titanium or stainless steel and two anodes of lead containing 0.05 pct ca. the electrode spacing was 5 cm. electrolyte was pumped to and from the cell by a chemical metering pump, while a small fraction of the metal ion content was deposited. the pregnant feed was stored in a 28liter tank and was preheated to 50° to 85° c. electrolyte was circulated within the cell by an external centrifugal pump, which had intakes located under the anodes and outlets spaced along tubing running under and parallel to the single cathode. the outlets were 0.5mmdiam holes drilled alternately at 22.5° from either side of the top center of the tubing at a spacing of 1.25 cm to provide upward jetting at a flow rate of 1.1 l/m. (see fig. 1.) evaporative losses and misting were minimized by floating polypropylene spheres, which covered the exposed electrolyte surfac see full list on 911metallurgist.com effect of nickel concentration the effect of nickel concentration in the electrolyte on current efficiency and energy consumption was determined by testing with electrolytes containing between 60 and 135 g/l ni. other variables were held constant at the initial levels described above. figure 3 shows that current efficiency increased from 60 to 72 pct, while energy consumption decreased from 2.25 to 1.86 kwhr/lb ni, as nickel concentration was increased. because the electrical energy consumption rate was continuing to decli effect of nickel extraction and hydrogen ion concentration the effect of nickel removal by electrodeposition is inherently associated with the hydrogen ion concentration because of the electrochemical reactions which take place, as follows: the electrode potential required for decomposing sulfate ions is much greater than for decomposing watertherefore, the sulfate decomposition reaction does not proceed. the hydrogen ions generated by the anode reaction are more easily reduced at the cathode than those of nickel and, in spite of their comparativel effect of current density the effect of increasing the cathode current density from 15 to 45 amp/ft² was tested at two extraction levels, 3.2 and 5.1 g/l, while again holding other variables constant at the initial conditionswith the exception, of course, of providing a corresponding flow rate of electrolyte. while only a slight increase in current efficiency was obtained2.6 and 3.3 pct, respectivelyat these two extraction levels, energy consumption increased 51 and 46 pct because of the increase in cell voltage fr see full list on 911metallurgist.com the combining of electrowinning with the solvent extraction step developed for the bureau process for lowgrade laterites must be done in a manner compatible with the requirements relating to the overall process. preferred flow and nickel transfer rates must be matched in the solvent extraction and electrowinning circuits. as a result, 1:1 aqueous to organic ratios are attained in the mixers during stripping. to avoid excessive solution recycle, a 5g/l or greater nickel extraction should be obtained from electrolyte as it passes through the cell. increasing the extraction from 3.2 to 5.0 g/l in the experimental cell under the initial conditions increased the energy consumption about 15 pct. increasing the temperature under the initial conditions to 65° c decreased energy consumption about 15 pct. therefore, it was decided to increase the temperature to at least 65° c in initial operations during subsequent integrated circuit tests. these parameters were tested in the experimental see full list on 911metallurgist.com cobalt electrowinning was patterned after the boulder city, nev., experiment station work where tests in nondiaphragm cells using cobalt sulfate electrolyte showed that current efficiency increased with concentration and temperature while energy costs decreased and plate character improved. pilot plant work at boulder city was conducted at 60° c because of rapidly increasing evaporation rate at higher temperatures and because higher zinc could be tolerated while producing good plate. although tests at cobalt concentrations above 70 g/l co appeared favorable, stronger electrolyte was not used because the preparation required filtration of nearly neutral solutions that became quite viscous at higher concentration. since the filtration would not be required in a solvent extractionelectrowinning operation, higher concentrations could be preferable. during the current investigation initial work with the experimental cell involved attempts to deposit cobalt on titanium starter blanks wit see full list on 911metallurgist.com the investigation of the effects of variables affecting nickel electrowinning has shown that electrical energy consumption increases with increasing extraction and current density and decreases with increasing temperature and concentration of metal ions. the presence of na2so4, as required for diaphragm cell operation, also decreases energy consumption and would be recommended, except that compatibility with solvent ion exchange was not determined. with solvent extraction, the nondiaphragm cell is satisfactory. specific conclusions as to optimum parameters were not reached because of opposing factors not subject to evaluation in this preliminary study and because of an interdependency with solvent extractionhowever, electrowinning at a temperature of 65° c or above was found to provide suitable values for current efficiency and energy consumption with an extraction per pass of 5 g/l or better. under these conditions nickel was electrowon at 2.10 and 2.30 kwhr/lb for extractions of see full list on 911metallurgist.com gold prospecting equipment gold fever
