With full vertical integration, Sunresin ensures quality, speed, and innovation from resin synthesis to complete plant delivery. The company is committed to sustainability, cost-efficiency, and technological advancement in separation processes for the mining, environmental, and chemical industries.
Why SepGold™?
Traditional large-scale gold extraction systems are ill-suited for small or scattered gold deposits. The high capital and operational costs often make them unviable. SepGold™ was designed to overcome this barrier—making low-grade, oxidized gold ores economically recoverable.
SepGold™ is ideal for:
• Heap or vat leach operations with filtered PLS
• Tailings and beneficiation waste
• Overburden and oxidation zones
• Remote or off-grid gold projects
Key Features of the SepGold™ Module
1. Mobile & Skid-Mounted: Easily relocatable via road or trailer
2. Modular & Scalable: Plant capacity grows by adding units
3. Low CAPEX and OPEX: Designed for efficiency in both investment and operation
4. Minimal Freshwater Use: Sorption and desorption share common reagents
5. Turnkey Delivery: Fully pre-assembled and tested prior to shipment
6. Remote Monitoring & Automation: Reduces labor and simplifies operation
7. Standardized Footprint: Frame fits in 40'HC shipping containers, matches trailer dimensions for seamless transport
Advanced Process Technology: Simulated Moving Bed (SMB)
• 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)

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.
