Post-Transitional/Semi-Precious Metals Producer Recovers Valuable Metals from Scrap Electronics Leachate
Project Overview
When a global materials manufacturer sought to expand its post-transitional and semi-precious metals production at its facility in Asia, the firm needed an efficient solution for salvaging valuable metals from scrap electronics waste. Leveraging its ion exchange (IX) technology, SAMCO delivered a recovery and purification system to maximize resources.
Objective
Recover post-transitional/semi- precious metals from pregnant leach solution (PLS).
Project specifications:
- Process 1000–2000 liters per day
Scope of Service
SAMCO delivered an IX-based recovery and purification system, with services encompassing detailed process, mechanical, and electrical design and engineering, controls integration, and system fabrication.
Challenges
- Complex contaminant streams
- High-purity solutions critical for production
Solution
SAMCO designed and constructed an IX system capable of a two- stage process to effectively isolate high-purity streams of the valuable metals. The system was contained within a prepackaged, skid-mounted design in order to facilitate rapid installation, and to compensate for limited operator availability, SAMCO installed programmable logic controllers (PLC) to automate flow, temperature, pressure, and resistivity monitoring.
Technology
SAMCO delivered a single packaged skid unit, including:
- IX pressure vessels and internals
- Effluent and influent pumps
- Multimedia filters
- Instruments and valves
- PLC controls
