BIF’s significance
A sedimentary rock with alternating layers of iron-rich minerals
- Linked to the Great Oxygenation Event
- Records ancient ocean chemistry and atmospheric changes
- Primary source of iron ore for steel production.
- Essential for construction, manufacturing, and infrastructure
Significant uses of Aluminum
Aerospace & Transportation – Lightweight, strong material for aircraft and vehicles.
Electrical Transmission – Power lines due to conductivity and corrosion resistance.
Packaging – Cans and foil for food preservation.
Significant uses of Copper
Electrical Wiring – High conductivity makes it essential for power grids and electronics.
Plumbing – Corrosion-resistant pipes for water systems.
Heat Exchange – Used in radiators, air conditioning, and refrigeration.
Significant uses of Zinc
Galvanization – Coating steel to prevent rust, crucial for construction and infrastructure.
Batteries – Component in alkaline and zinc-carbon batteries.
Significant uses of Lead
Radiation Shielding – Protects against X-rays and nuclear radiation.
Ammunition – Bullets and weights due to density.
Significant uses of Titanium
Aerospace & Military – High strength-to-weight ratio for aircraft and submarines.
Medical Implants – Biocompatible material for bone and dental implants.
Pigments (Titanium Dioxide, TiO₂) – Used in paints, sunscreen, and cosmetics.
An undesirable byproduct of smelting sulfide ore minerals to obtain their metals
Sulfur dioxide (SO2)
Contributes to acid rain, which damages ecosystems, buildings, and water source
Causes respiratory issues and worsens air quality
Can form sulfate aerosols that affect weather pattern
