Gold Refining Equipment

In the precious metal supply chain, gold refining has long been the critical bridge between unrefined scrap, mined ore, and high-purity bullion. For decades, traditional pyrometallurgical smelting served basic melting needs, but it routinely struggled with high metal loss, inconsistent purity, and severe environmental pollution. As the industry demands stricter quality control and zero gold loss, advanced chemical purification has replaced crude smelting as the gold standard.

SuperbMelt’s gold refining equipment represents the next generation of this processing evolution, harnessing high-precision Aqua Regia (royal water) technology to chemically dissolve and isolate impurities at the molecular level. Engineered for precision and operational flexibility, our systems feature a standardized 3–10 kg per batch capacity that reliably yields 99.99% (4N) pure gold, with modular options available to match your exact production scale.

Our chemical processing stage seamlessly integrates high-purity titanium reactors for aqua regia dissolution, automated stirring PP reduction tanks for optimal gold precipitation, and mobile filter carts for rapid sponge gold recovery. Operating fume hoods provide isolated environments for both raw material pre-treatment and final sponge gold washing, ensuring a clean feed and maximum yield.

To guarantee maximum workplace safety and environmental compliance, the entire system operates under a dedicated negative-pressure exhaust architecture. By pairing reaction fume hoods with multi-stage scrubber towers and high-efficiency centrifugal fans, all acidic mist and hazardous fumes are fully neutralized before discharge. This integrated approach allows refiners and jewelers to transform raw scrap into investment-grade gold with zero acid leakage and absolute purity control.
