Battery
Lithium is central to modern rechargeable smartphone batteries. Depending on battery chemistry, cobalt, nickel, manganese, graphite, copper, and aluminum may also play important roles.
RESOURCE USE GUIDE
What Minerals and Metals Are Used in Smartphones?
A smartphone may fit in your hand, but it depends on a surprisingly wide range of natural resources. Copper carries power and signals, lithium and cobalt support the battery, gold helps make reliable electrical connections, and specialty materials help create the screen, speakers, chips, camera, and vibration system.
SMARTPHONE ANATOMY
Where the Resources Go
Different models and component designs use different material combinations.
02
Circuit Boards & Electrical Contacts
Copper carries electrical signals and power through the device. Gold and silver are used where reliable conductivity and resistance to corrosion are especially important.
03
Processors & Electronic Components
Silicon forms the basis of semiconductor chips, while materials such as tantalum, tin, tungsten, and gallium can appear in specialized electronic components.
04
Speakers, Cameras & Vibration
Small high-strength magnets can use rare earth elements. Copper wiring, specialty metals, glass, and other materials support cameras, speakers, microphones, and haptic systems.
BATTERY MATERIALS
The Resources Behind the Battery
Li
Lithium
Lithium helps enable rechargeable batteries with high energy density, making it one of the most recognizable materials associated with smartphones and portable electronics.

ELECTRONICS
Small Amounts. Critical Jobs.
Some of the most valuable metals inside a smartphone may be present only in small quantities, but their physical properties make them extremely useful for miniaturized electronics.
Copper
Conducts electricity through circuit boards, wiring, connectors, and charging systems.
Gold
Used in selected contacts and connectors because it conducts electricity and resists corrosion.
Silver
A highly conductive metal used in some electrical and electronic applications.
Tin
Widely associated with solder used to join electronic components.
Tantalum
Useful in compact capacitors where high performance is needed in very little space.
Tungsten
Used in specialized components and has historically been associated with vibration mechanisms and electronics.
SCREEN & STRUCTURE
More Than Metals
Smartphone construction also depends on important nonmetallic mineral resources. Silica is central to glass production, while silicon is essential to semiconductor technology.
Si
Silicon
Refined silicon is fundamental to the semiconductor chips that process information inside modern electronics.
SiO₂
Silica
Silica-based materials are foundational to the glass used in smartphone displays and protective surfaces.
Al
Aluminum
Aluminum can be used in structural housings, frames, internal components, and battery-related applications.
RESOURCE IMPORTANCE
Why Smartphone Materials Matter Globally
01
Huge Device Volumes
Small amounts of a material in one phone can become substantial when multiplied across hundreds of millions of devices.
02
Complex Supply Chains
Mining, refining, processing, component manufacturing, assembly, and recycling may occur in several different countries.
03
Specialized Materials
Many smartphone components rely on materials with specific electrical, magnetic, thermal, or structural properties.
04
Recycling Potential
Retired electronics contain metals and other materials that may be recovered rather than permanently lost to waste streams.
GLOBAL SUPPLY
Where Smartphone Resources Come From
Lithium
Major supply comes from countries including Australia,
Chile, Argentina, and China.
Cobalt
Mine supply is strongly associated with the Democratic
Republic of the Congo, with additional production elsewhere.
Copper
Major mining regions include Chile, Peru, the Democratic
Republic of the Congo, China, and other producers.
Rare Earths
Mining and especially processing capacity are concentrated
in a relatively small number of countries.
Nickel
Important production comes from Indonesia and several
other major mining countries.
Production rankings and quantities should be date-stamped on individual resource profiles using current authoritative data.
RECYCLING & RECOVERY
What Happens to the Resources When a Phone Is Retired?
Old smartphones can contain recoverable copper, gold, silver, cobalt, and other materials. Recovery is not as simple as melting down a single metal, however. A phone is a compact mixture of electronics, plastics, glass, adhesives, batteries, and many different materials.
Specialized recycling systems can separate and process electronic waste so valuable resources can re-enter manufacturing supply chains.
Why Recovery Matters
- Reduces material sent to disposal.
- Recovers valuable metals from existing products.
- Can reduce demand for some newly mined material.
- Supports more circular resource use.
- Helps manage batteries and electronics responsibly.
