AI Technical Summary
Technical Problem
Conventional methods for recovering valuable metals from waste, such as incineration ash, are inefficient and require improvement.
Method used
A waste treatment device equipped with an eccentric eddy current separator, operating at specific conditions, including a conveyor belt, magnetic drum, and agitator, which separates valuable metals like gold, silver, copper, and platinum by applying a strong magnetic field and controlled rotation speed, along with pretreatment processes to optimize metal recovery.
Benefits of technology
The device achieves more efficient separation and recovery of valuable metals by enhancing the repulsive force and distinguishing between metals and other substances, improving the overall efficiency of the recovery process.
