Zinc

What is Zinc?

Zinc (Zn) is a chemical element classified under group 12 of the periodic table. It is the fourth most widely used metal in the world, following iron, aluminum, and copper, and has significant industrial and biological applications. Biologically, zinc is essential for both plants and animals, playing key roles in various bodily functions, including cell and enzyme production, as well as the metabolism of carbohydrates and fats. In this article, we will explore zinc in detail, including its characteristics and uses.

Characteristics of Zinc

Zinc is a soft, non-ferrous metal with a bluish-silver color. It has low tensile strength and is categorized as a brittle metal, which limits its use in applications where strength is required. Zinc has a hexagonal crystal structure and a lower density compared to iron. It becomes ductile and malleable in specific temperature ranges (212°F to 302°F). Although zinc itself has moderate conductivity, it possesses favorable chemical properties.

Applications of Zinc

Zinc has a variety of applications, including:

  • Electrical and electronic equipment
  • Automotive industry
  • Pharmaceutical industry
  • Paint and printing industry
  • Production of various alloys like brass and bronze
  • Components of batteries
  • Metal coating to prevent corrosion
  • Other industries such as rubber manufacturing and agriculture

Zinc Production Process

Zinc is produced from sulfide ores that may contain cadmium, lead, iron, silver, and others. These ores are found in countries like China, Japan, Australia, and North and South America. Two primary processes for producing zinc include:

Electrolytic Process

Over 90% of the zinc produced globally is obtained through the electrolytic process, which involves several stages:

  1. Concentration of ore
  2. Roasting of the ore
  3. Conversion of zinc oxide to sulfate
  4. Electrolysis of zinc sulfate solution

Thermal Process

The thermal process uses ISF furnaces. However, due to high gas emissions and energy consumption, this method is less favored in Europe in favor of the electrolytic process. In this method, the dampers, zinc, and lead are produced.
