Silver is a precious metal with excellent conductivity, playing a key role in our electronic devices with circuits, switches, and connections. As the demand and price for silver are increasing, people now search for this valuable resource in discarded electronics.
This guide will show you where to find scrap silver in electronics. You’ll learn which parts contain the most silver and how to get the most out of your recovered silver.
Electronics recycling offers both environmental benefits and potential profits. You can turn electronic waste into valuable silver while keeping harmful materials out of landfills.
Let’s explore the world of scrap silver recovery, starting with knowing where it hides!
Where to Find Scrap Silver in Electronics
Let’s examine the specific electronic items that contain silver!
Printed Circuit Boards (PCBs)
Electronics contain valuable precious metals that can be profitable to salvage. Circuit boards serve as a major source, with one ton of computer PCBs can yield over $10,000 worth of gold alone, along with significant silver content, according to Techreset.
PCBs are found in computers, smartphones, tablets, and gaming consoles. They contain traces of silver in their components and connections. Many recyclers focus on PCBs due to their high precious metal content and relative ease of collection.
Relays and Switches
Almost every electronic device with an on/off function contains silver contacts in its switching mechanisms. Silver is the preferred metal for switches due to its excellent conductivity. Common items containing silver switches include:
- Television sets and remotes
- Microwave ovens
- Vacuum cleaners
- VCR and DVD players
- Kitchen appliances
- Power tools
- Home electronics
- Light switches
While individual switches may contain small amounts of silver, collecting multiple devices can accumulate worthwhile quantities.
Connectors and Terminals
Electronic connectors and terminals contain valuable silver plating that prevents oxidation while maintaining excellent conductivity. Common sources include USB ports, charging docks, and audio/video connectors like HDMI and RCA jacks. Computer motherboards are silver-rich connectors, including PCIe slots, RAM slots, and power supply connections. Network interface cards and industrial control systems also use silver-plated terminals.
Capacitors (older types)
Older capacitors that were manufactured before the 1990s often contain significant amounts of silver components.
- Large electrolytic capacitors found in old power supplies and amplifiers contain considerable silver.
- Ceramic capacitors commonly used in old television sets and stereo equipment may contain silver plates or silver-based internal components.
- Mica capacitors, particularly those in antique radios and early electronic devices, were made with silver plates and connections.
- Tantalum capacitors from early computers and military equipment sometimes used silver in their construction.
Older Cell Phones and Computers
Early-generation computers used silver in their keyboard membranes to provide reliable contact points for keystrokes. Computer chips from this era also often incorporated silver in their internal wiring and connection points. Circuit paths on motherboards and expansion cards contained thicker silver traces than current designs. Meanwhile, early mobile phones used silver contacts in their keypads, antenna connections, and internal circuitry.
RFID Tags (Radio-Frequency Identification)
RFID technology uses silver in its antenna systems, making these small tags a huge source of precious metal. Based on SilverForte, RFID tags may contain small amounts of silver, with estimates around 10 milligrams per tag, depending on the model and manufacturer.
As RFID tags replace traditional barcodes in retail, warehousing, and logistics, their prevalence continues to grow. The silver content makes them valuable for large retail operations or distribution centers where tags are regularly disposed of during inventory management processes.
Solar Panels (Photovoltaic Cells)
Solar panels represent a major industrial use of silver where to find scrap silver in electronics. Based on the data from the International Renewable Energy Agency (IRENA), between 2010 and 2019, solar panel costs fell by 82%, driven by technological advancements, including improved efficiency and manufacturing processes. Silver remains an essential material in photovoltaic cells. Silver paste is used in the conductive lines on solar cells to carry electricity generated by sunlight. Modern solar panels use silver in their busbars, contact points, and internal wiring.
The metal’s superior conductivity properties make it irreplaceable in high-efficiency solar cell production. As renewable energy adoption grows, solar panels become an increasingly important source of recoverable silver.
Industrial Electronic Equipment
Silver appears throughout industrial electronic equipment with the key components as below:
- Control panel contacts and switches in manufacturing equipment
- Industrial sensors and monitoring devices
- Power distribution systems and circuit breakers
- Medical equipment and diagnostic machines
- Industrial-grade computing systems
- Process control equipment
- Telecommunications infrastructure
- Heavy machinery control circuits
The high-reliability requirements of industrial equipment mean these components often contain larger amounts of silver than consumer electronics.
Where to Find Scrap Silver in Mexico?
In Mexico, the electronics sector stands as a primary source of scrap silver, particularly through household devices.
Household Electronics
The best sources come from older electronic devices. Computers and laptops from the 1990s and early 2000s contain higher amounts of silver than modern models. Older cell phones, particularly pre-smartphone models, often yield more precious metals.
Old televisions, stereo equipment, DVD players, and VCRs contain silver in their switches and circuit boards. Printers and scanners include silver components in their control panels and internal mechanisms.
Recycling Centers and E-Waste Depots in Mexico
Mexican recycling centers and e-waste facilities serve as central hubs for electronic materials. These locations regularly process large volumes of discarded devices, making them valuable spots for where to find scrap silver in electronics.
Local Electronics Repair Shops
Local electronics repair shops frequently accumulate broken devices and spare parts, which provide steady access to silver-containing components.
Industrial Sources
Industrial sources present another source for silver scrap, specifically through electronic manufacturing waste. However, this path requires extra caution. Mexican law strictly regulates industrial scrap collection. Unauthorized collection or processing could result in legal penalties and safety hazards.
Before starting any collection efforts, research local regulations and obtain necessary permits. Always wear appropriate safety gear when handling electronic waste, and process materials in well-ventilated areas.
