Mobile Sorption Module for Gold Extraction

Unlocking the Potential of Small-Scale Gold Deposits

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.

About Sunresin

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.

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

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

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:

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)

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.
