Smartphone Composition and Elements

Elements Found in Smartphones

• Over 70 elements are utilized in smartphone construction, including plastic and metal casings, battery, touchscreen, and electronics.
• These elements originate from both living organisms and non-living resources like rocks and minerals.

Materials in Screens and Chips

• Glass is primarily made from silica sourced from quartz sand.
• Silicon, essential for computer chips, also comes from quartz sand.

Metals Used in Smartphones

• Aluminum, used to make glass shatter-resistant, is derived from bauxite ore.
• Indium, which enables touchscreen functionality, is found alongside copper and lead in deposits.

Rare Earth Elements

• Rare earth minerals such as bastnäsite and monazite are vital for producing magnets in speakers and microphones, as well as for vibration mechanisms and vibrant screen colors.

Components Bindings and Wiring

• Tin, present in touchscreens and used as solder, come from the cassiterite mineral found in igneous rocks and some sediments.
• Copper is essential for wiring and is often found in conjunction with indium.

Battery Materials

• Lithium for rechargeable batteries is extracted from lithium-rich brines, commonly harvested via solar evaporation ponds.

Smartphone Casings

• Smartphone cases can be constructed from carbon sourced from oil or graphite deposits, enhancing durability.
