Definitions

  • the invention is related to additives for zinc electrowinning that inhibit hydrogen evolution and/or improve current efficiency for zinc electrodeposition, specifically cetylpyridinium-based additives.
  • Cetylpyridinium chloride (CPC), a cetylpyridinium salt, was tested as an additive in a zinc electrowinning process in two separate zinc electrowinning electrolyte compositions: 1) with antimony and 2) with both antimony and glue.
  • the CPC additive had the most significant influence in the presence of antimony or antimony+glue combination, where it increased the current efficiency by 23.2% and 7.6%, respectively. Moreover, the presence of 0.05 mM CPC did not increase the overall cell voltage.
  • a constant current of 0.045 A representing an electrowinning current density of 450-amperes/meter 2 , was applied for either 4 or 20 hours to a non-agitated electrolyte.
  • the electrode assembly was removed from the glass beaker, rinsed with distilled water and the cathode deposit carefully scraped off and weighed with four digits precision using a digital Mettler AE 100 analytical balance.
  • the test cells were rinsed between experiments with distilled water and acetone in order to remove traces of the organic additives. Replicates were also performed and the standard deviation was estimated.
  • CPC cetylpyridinium chloride
  • Antimony (Sb) in 0.04 mg/l (milligrams/litre) concentration was added as antimony—potassium tartrate to the zinc electrowinning electrolyte. Both four and twenty hour runs were performed. The experimental results of the four-hour runs are summarized in Table 1.
  • Example 3 Similar experiments to those in Example 1 were performed with an electrolyte containing 0.04 mg/l of Sb and 10 mg/l of glue (e.g. “pearl glue” supplied by Hudson Industries, Johnstown, N.Y.). Both 4 and 20 hour runs were carried out. The effect of the CPC additive on the zinc electrowinning current efficiency in the 4 hour runs is shown in Table 3.
  • glue e.g. “pearl glue” supplied by Hudson Industries, Johnstown, N.Y.
  • the cell voltage is another important figure of merit of the electrowinning process.
  • An increase in the cell voltage represents an increase in the amount of energy required and, therefore, a less efficient electrowinning process.
  • Table 5 shows that using 0.05 mM CPC in conjunction with Sb and glue did not induce an increase of the cell voltage. TABLE 5 Effect of CPC on the average cell voltage in 4 hour experiments with 0.04 mg/l Sb and 10 mg/l glue in the electrolyte. Conditions: Temperature: 37° C. Time: 4 hours Average cell voltage (V) No additive 2.83 CPC 0.05 mM 2.83
