Mobile Sorption Module for Gold Extraction
Mobile Sorption Module for Gold Extraction
As the gold value continues to rise, small-scale and previously uneconomical gold resources are gaining strategic value. These include tailings, weathered crusts, overburden dumps, and off-balance stockpiles—often overlooked due to their challenging scale and low-grade nature.
SepGold™ by Sunresin offers a turnkey, mobile, and cost-effective solution specifically engineered to recover gold from these complex deposits. Utilizing proprietary resin technology and a compact, modular design, SepGold™ enables mining operations to transform marginal resources into profitable production sites.
Sunresin New Materials Co., Ltd. is a global leader in synthetic ion-exchange resins and adsorbent materials, headquartered in Xi’an, China. As the largest manufacturer of ion-exchange resins in China and a publicly listed company with a market capitalization of $4.5–5.4 billion USD, Sunresin provides turnkey EPC (Engineering–Procurement–Construction) solutions for more than 25 industrial applications across the globe.
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.
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.
- Heap or vat leach operations with filtered PLS
- Tailings and beneficiation waste
- Overburden and oxidation zones
- Remote or off-grid gold projects
- Mobile & Skid-Mounted: Easily relocatable via road or trailer
- Modular & Scalable: Plant capacity grows by adding units
- Low CAPEX and OPEX: Designed for efficiency in both investment and operation
- Minimal Freshwater Use: Sorption and desorption share common reagents
- Turnkey Delivery: Fully pre-assembled and tested prior to shipment
- Remote Monitoring & Automation: Reduces labor and simplifies operation
- Standardized Footprint: Frame fits in 40’HC shipping containers, matches trailer dimensions for seamless transport
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:
- Gold sorption from pregnant leach solution (PLS)
- Backwashing of solids
- Upgrading of gold loading from desorbate
- Countercurrent desorption
- 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 |
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
