  "field": "Environment",
  "definition": "pyrometallurgical methods, including distillation, or hydrometallurgical methods, including electrowinning, calcination, leaching, or purification. The electrowinning process is most commonly used. Electrowinning uses an electrolytic cell to reduce the zinc. An electric current is run from a lead-silver anode through a zinc solution. The zinc deposits on an aluminum cathode and is harvested. The zinc is then melted and cast into ingots.",
