Sunresin outlines mobile gold sorption module for remote mining sites

Sunresin is pitching a certified mobile gold sorption module in China as an alternative to permanent CIL and CIP plants for satellite ore bodies, low-grade deposits and short-life mines. The company says the relocatable system can cut commissioning time, reduce infrastructure needs and improve recovery from complex ores, including preg-robbing material.

Why it matters: - Mining operators are facing lower-grade reserves and higher capital pressure, making permanent gold processing plants harder to justify. - Relocatable recovery equipment can be deployed to remote, short-life or satellite deposits without the cost of building fixed infrastructure. - Mobile sorption modules can also help process ores with preg-robbing carbon, where conventional recovery systems can lose gold yield.

What happened: - Sunresin published a guide on a Certified Mobile Gold Sorption Module in China for gold extraction. - The guide positions the module as a relocatable processing unit for precious-metal recovery at remote mining sites. - Sunresin links the module to its Seplite product line and to its mobile gold extraction and SepGold resin technology pages: More information and the resin technology overview.

The details: - The module is built on heavy-duty skid frames sized to fit standard 40-foot High Cube shipping container dimensions. - Standard flatbed trailers or cargo vessels can transport the equipment without specialized logistics gear. - The system arrives with key sub-systems preassembled, including solution pumps, automated flow valves, digital sensors and centralized control panels. - Factory Acceptance Testing is used before shipment to verify valves, pumps and electronics. - Site setup requires compacted ground or basic concrete pads, primary fluid lines and local power generators. - Sunresin says the plug-and-play design can cut commissioning from months to a few days. - The modular design can be expanded by adding parallel sorption modules as production grows. - The core process uses Simulated Moving Bed continuous sorption equipment with automated valve switching. - The cycle includes gold sorption, backwashing, upgrading gold loading, countercurrent desorption and final resin washing. - The resin system uses Seplite gold-selective ion exchange resins engineered to capture gold cyanide complexes such as Au(CN)2-. - The company says synthetic resins help prevent losses tied to preg-robbing carbonaceous ore. - The guide says resin desorption occurs at ambient temperature and atmospheric pressure, unlike activated carbon regeneration, which requires high-temperature thermal treatment. - That operating profile lowers power use and operating expense. - The module can be used in heap leaching and vat leaching to process pregnant leach solution near the leach pad boundary. - The compact footprint reduces the need for long pipeline runs to solution ponds. - The equipment can also process legacy tailings and historical waste dumps on site. - For remote operations, the modules are designed for continuous performance with minimal manual intervention. - The guide cites a case operating at about 1.08 grams per cubic meter gold concentration, pH 10.3 and 80.4 cubic meters per hour, with sorption recovery up to 90%. - Sunresin describes itself as a publicly listed company with stock code 300487. - Sunresin says its business spans custom resin synthesis, equipment fabrication and EPC delivery. - The company says it handles metallurgical testing, flowsheet design, module fabrication and site startup. - Sunresin says ISO quality systems govern production from raw material inspection to final module testing. - The website lists product options, technical specifications and global service capabilities at Sunresin's official site.

Between the lines: - The pitch reflects a broader shift toward modular mining equipment that can be moved as ore bodies change and project lives shorten. - The emphasis on resin chemistry suggests the main competitive edge is not just mobility, but better recovery from complex feed streams that challenge carbon-based systems. - Sunresin is also bundling materials, equipment and EPC services, which can reduce integration risk for mine operators.

What's next: - Mining buyers evaluating modular recovery systems will likely compare resin selectivity, transport constraints, power needs and site setup time before buying. - Operators will also look at spare-parts support, resin lifecycle management and long-term technical service before deployment. - Sunresin says detailed specifications and service information are available through its website.

The bottom line: - Sunresin is betting that portable, resin-based gold recovery can make marginal deposits economically workable without the cost of building permanent plants.
