What is a "Precious Metal Recovery System"?
This is a group of engineered equipment designed to efficiently recover and refine high-purity gold, platinum, palladium, and other precious metals contained in waste plating solutions, process effluents, and chemical compounds. By integrating multiple technologies—including electrolysis, ion exchange, and activated carbon adsorption—the system maximizes recovery efficiency and aims to eliminate precious metal discharge in wastewater. Its chemically resistant construction and high operability enable safe in-factory operation while contributing to operational cost reduction.

We provide systems to recover precious metals from precious metal plating lines.

We offer proposals for optimal recovery systems to suit the customer’s specifications, with the goal of reducing precious metal content in wastewater to nearly “zero.”
