Mobile Sorption Module for Gold Extraction

At the core of SepGold™ is a Simulated Moving Bed (SMB) design—a highly efficient configuration for continuous gold recovery. In this system:

• Resin columns remain fixed; their function cycles automatically
• Each column operates in stages:

1. Gold sorption from pregnant leach solution (PLS)
2. Backwashing of solids
3. Upgrading of gold loading from desorbate
4. Countercurrent desorption
5. Resin washing

• Automated valve switching controls the entire cycle without manual handling
• Columns and cycle times are optimized based on specified data (gold concentration, pH, resin kinetics)

Parameter	Value
PLS Gold Concentration	1.08 g/m³
pH	10.3
Resin Capacity	560 g/m³
Flow Rate	80.4 m³/h
Sorption Recovery	90%
Annual Output	~680 kg of gold

 

 

 

Deployment and Logistics

SepGold™ modules are:

• Shipped fully pre-assembled in containerized frames
• Designed to fit 40-foot high cube containers
• Sized to match standard trailer capacity for direct overland transport
• Plug-and-play: Only utility connections (water, power) are needed on-site
• Pre-integrated with pumps, tanks, valves, sensors, and automation systems for rapid startup

 

 

Global Applications

SepGold™ has been developed with international deployment in mind. The system is suitable for:

• Artisanal and small-scale mining (ASM)
• Remote sites without infrastructure
• Seasonal or pilot projects
• Environmentally sensitive operations seeking low-impact gold recovery

Applications are already being explored across Africa, Latin America, Central Asia, and Southeast Asia, supported by Sunresin’s global engineering and service teams.
