A compact, high-efficiency system engineered for advanced precious metal recovery — delivering up to 99.8% purity with scalable, modular design.
System Overview
What It Is
A modular electrowinning system (1–8 cells) designed for selective recovery of gold, silver, platinum, rhodium, and other valuable metals.
Key Components
Graphene-coated graphite anodes — enhance electron flow and efficiency
Vertically rotating titanium cathode — ensures uniform deposition and easy metal removal
Modular cell design — scalable from 1 to 8 cells
Working Principle
The rotating cathode ensures uniform metal deposition across the entire surface, maximizing recovery efficiency and simplifying the harvesting process.
Applications
E-Waste & Electronics
Electronic plating waste and e-waste streams containing recoverable precious metals.
Jewelry Industry
Plating baths, drag-out, strip and rinse solutions, and jewelry stripping solutions.
Mining Operations
Gold and silver mining operations requiring high-purity metal recovery from process solutions.
Photographic Waste
Recovery of silver and other metals from photographic waste solutions.
Industrial-Grade Design
Built for demanding industrial environments, the rotating electrowinning system combines robust stainless steel construction with precision engineering — delivering consistent, high-purity results at scale.
Cell Models & Capacity
All cells operate at 4.5V. Capacity scales linearly from 1 to 8 cells, with gold recovery up to 2.94 kg/hr and silver up to 4.83 kg/hr.
Scalable Capacity at a Glance
Gold and silver recovery capacity scales linearly with each additional cell module, allowing operations to precisely match throughput requirements without over-investing in capacity.
