Jin Yin (金银) is a leading research and development company specializing in eco-friendly gold leaching chemistry. Headquartered at Qingpu Industrial Park, No. 388 Huqingping Road, Shanghai, we are the scientific backbone behind five globally recognized gold leaching brands.
Our mission is to continuously advance the performance, safety, and environmental profile of non-cyanide gold recovery reagents — partnering with Sandioss, CNFREE, YX500, JinChan and Eco-Goldex to maximize their effectiveness across every ore type and mining condition worldwide.
With a team of leading chemists and metallurgists, Jin Yin's proprietary liquid formulation research ensures our partner brands stay at the cutting edge of gold leaching technology.
Jin Yin provides the research, formulation chemistry, and continuous performance enhancement for five of the world's leading non-cyanide gold leaching liquid agents. Each brand is supported by our dedicated R&D team to deliver maximum gold recovery results.
High-efficiency non-cyanide leaching liquid for heap & tank operations. Jin Yin R&D enhances its dissolution kinetics and selectivity.
Flagship zero-cyanide agent for Au, Ag & Cu recovery. Our research optimizes its wide ore compatibility and pH stability.
Concentrated liquid for refractory & low-grade ores. Jin Yin boosts its selectivity for gold over base metals.
For complex polymetallic ores. Our R&D delivers stability in high-temperature & high-salinity mine environments.
Ultra-low toxicity, rapid biodegradation. Jin Yin drives its performance near sensitive ecosystems & protected zones.
Our R&D team engineers molecular-level improvements to leaching reagents — increasing gold ion mobility and dissolution rates without adding toxicity.
We continuously test and optimize each partner brand against real ore samples from 30+ countries, ensuring every formula performs at its absolute peak.
Every enhancement undergoes rigorous environmental testing. We raise recovery rates while simultaneously improving biodegradation profiles.
Our research is validated across 600+ real mine projects in 30+ countries — from West Africa heap leach operations to Southeast Asian alluvial deposits.
Jin Yin's lab analyzes your ore type, grade, and mineralogy to select and tune the right partner brand formula for your specific deposit.
We optimize the selected leaching agent's concentration, additives, and pH profile specifically for your ore conditions.
The enhanced liquid agent is deployed on-site — heap leach, tank leach, or agitation system — with Jin Yin technical supervision.
Achieve up to 99%+ gold recovery with continuous performance monitoring and ongoing R&D support throughout operations.
Jin Yin and partner brands presenting at global mining industry events — showcasing the latest in eco-friendly gold leaching technology to operators worldwide.
Connecting with mining operators, metallurgists and industry partners — building relationships that drive better gold recovery solutions worldwide.
On-site R&D visits to client mining operations to validate formula performance and fine-tune reagent dosing in real conditions.
Regular technical summits with our five partner brand teams to align on R&D roadmaps and performance improvement targets.
Continuous in-house research sessions testing new molecular formulation approaches for enhanced gold dissolution and eco-safety.
