Frequently Asked Questions
How Much Gold Can Be Recovered From a Single Smartphone?
According to industry data, a single smartphone contains between 7 to 36 milligrammes of recoverable gold, primarily found in the device’s circuit board and components.
This precious metal is used for connectors, contacts and bonding wires due to its superior conductivity.
While the amount may seem miniscule, when scaled across billions of devices, it represents a significant opportunity for resource recovery through proper recycling processes.
What Happens to Gold in Smartphones When They Are Recycled?
When smartphones are recycled, their gold-containing components undergo a systematic recovery process.
First, devices are disassembled to isolate circuit boards and connectors. These parts are then ground into fine particles and processed through chemical or physical separation methods, such as leaching.
The extracted gold is purified, melted down, and ultimately repurposed for manufacturing new electronic components or other industrial applications, creating a sustainable cycle of precious metal reuse.
Are There Alternatives to Using Gold in Smartphone Manufacturing?
Several viable alternatives to gold exist in smartphone manufacturing.
Copper offers similar conductivity at lower costs, though it requires protective coating against oxidation.
Silver provides excellent conductivity and can be used with innovative alloys like LUNA® that reduce environmental impact.
Nickel alloys present cost-effective solutions with good corrosion resistance, while platinum serves in specialised applications where superior durability is paramount.
These alternatives help manufacturers reduce reliance on precious metals whilst maintaining performance.
Does the Presence of Gold Affect Smartphone Prices Significantly?
The presence of gold in smartphones has a minimal impact on retail prices.
With only seven milligrams of gold per device, valued at approximately $0.38, it represents a tiny fraction of overall manufacturing costs.
While gold remains essential for its conductive properties and reliability, manufacturers have optimised its usage through efficient plating techniques.
Other factors like labour, technology development, and marketing have far greater influence on smartphone pricing than gold content.
How Do Manufacturers Ensure Gold Components Don’t Corrode Over Time?
Manufacturers employ multiple strategies to protect gold components from corrosion.
They utilise electroplating techniques combined with corrosion-resistant underlayers like nickel-tungsten alloys. Components are assembled in controlled environments and sealed within protective casings.
Additional measures include applying platinum or rhodium top coatings and implementing layered coating stacks.
Regular durability testing under various conditions, including humidity and salt exposure, guarantees the long-term integrity of these protective systems.
