The source of zinc is the ore raw material, which is usually in a sulfide state, and zinc is mainly represented by sphalerite (ZnS). Ores are always complex, contain, in addition to zinc, lead, copper, iron, silver, etc. Recently, secondary raw materials have been used in countries with high consumption.

• Approximately 50% of world zinc production is spent on coating iron products to protect them from rust.
• More than 30% of all zinc production in the world is used for alloy production. An alloy of zinc with copper and tin is called bronze. Various types of bronzes are widely used in mechanical engineering. Zinc alloys with copper and nickel are called nickel silver and nickel silver. Due to its ability to produce alloys with silver and gold, zinc is used in metallurgy to extract precious metals.
