Memory Stick Recovery
Memory stick recovery holds high value because: each ordinary memory stick contains approximately 0.01 grams of gold. As core components of electronic devices with large market inventory and rapid consumer electronics replacement cycles, their massive quantity and gold content make them highly valued by memory stick recovery companies.
Precious Metal Locations in Memory Sticks
Gold primarily exists in contact points. During memory stick recovery, gold can be separated through electrolysis. Silver is distributed across solder joints, pin coatings, and circuit board traces, enhancing conductivity and connection reliability. Silver can be extracted via oxidation leaching.
Common Low-Cost Memory Stick Recovery Steps
1. Submerge damaged memory sticks into an electrolytic tank containing electrolyte solution for electrolysis
2. After electrolysis completes, replace cathode plates to recover raw copper
3. Supplement electrolyte solution in the memory stick recovery tank for secondary electrolysis
4. After reaction completes, recover raw gold powder from the tank’s cathode
5. Collect leachate for additional electrolytic recovery
