    • Aerospace: Aluminum is lightweight and corrosion-resistant, making it ideal for aircraft and spacecraft manufacturing.
    • Construction: Used in windows, doors, and structural elements due to its lightweight nature and resistance to rust.
    • Packaging: Aluminum is used for making cans, foil, and food packaging.
    • Transportation: Used in cars, bicycles, and other transportation systems for weight reduction.
  • Example: Australia is the largest producer of bauxite, which is processed into aluminum.

6. Lead

  • Mining Type: Extracted through underground mining and open-pit mining.
  • Industrial Applications:
    • Batteries: Lead-acid batteries are widely used in vehicles and backup power systems.
    • Shielding: Lead is used in radiation shielding, particularly in medical and nuclear settings.
    • Ammunition: Used in the production of bullets and shotguns.
    • Construction: Lead is used in certain types of building materials like roofing and plumbing.
  • Example: China and Australia are leading producers of lead.

7. Zinc

  • Mining Type: Extracted via open-pit mining and underground mining.
  • Industrial Applications:
    • Galvanization: Zinc is primarily used for galvanizing steel to protect it from corrosion (e.g., in pipes, roofing, and other structures).
    • Alloys: Zinc is used in various alloys such as brass, which is used in coins, musical instruments, and hardware.
    • Batteries: Zinc is a key component in batteries like zinc-carbon and alkaline batteries.
    • Agriculture: Zinc is an essential nutrient for plants, and zinc-based fertilizers are used to promote growth.
  • Example: China and Peru are major zinc producers.

8. Nickel

  • Mining Type: Extracted through open-pit mining, underground mining, and lateritic mining.
  • Industrial Applications:
    • Stainless Steel: Nickel is a key component in making stainless steel, which is used in everything from kitchenware to structural components.
    • Batteries: Nickel is a crucial part of lithium-ion batteries, used in electric vehicles and electronics.
    • Aerospace and Defense: Nickel alloys are used in jet engines, turbines, and other high-temperature applications.
  • Example: Indonesia, Philippines, and Russia are major producers of nickel.

9. Silver

  • Mining Type: Extracted through underground mining, open-pit mining, and heap leaching.
  • Industrial Applications:
    • Electronics: Silver is used in electrical components like switches, circuits, and conductors because it is an excellent conductor of electricity.
    • Solar Panels: Silver is used in photovoltaic cells for solar energy generation.
    • Jewelry: Silver is widely used in jewelry due to its lustrous appearance and relatively low cost compared to gold.
    • Currency: Historically, silver has been used in coins and as a store of value.
  • Example: Mexico, Peru, and China are major silver producers.

10. Uranium

  • Mining Type: Extracted through open-pit mining, underground mining, and in-situ leaching.
