Precious Metal Refining

DELMER Precious Metal Refining & Plating Equipment provides industrial systems for gold, silver, platinum and rhodium refining, precious metal recovery, assay laboratories and electroplating. DELMER supplies equipment and turnkey process solutions for jewellery manufacturers, refineries, recyclers, laboratories and industrial users.

Precious Metal Refining Equipment

Our refining systems are designed for different precious-metal feedstocks, capacities and process requirements. Solutions include gold refining plants, silver electrolysis systems, tumbler-type gold refining systems, precious metal recovery from e-waste and supporting refinery equipment.

Gold Refining

DELMER gold refining equipment supports applications involving gold alloys and suitable precious-metal feedstocks. Available systems can be configured for laboratory, small-batch and industrial refining requirements, depending on feed composition, capacity and required purity.

Silver Refining & Electrolysis

DELMER silver electrolysis systems are available in multiple capacities for continuous or batch-oriented refining applications. Equipment selection depends on silver feed purity, anode preparation, required throughput and plant configuration.

Precious Metal Recovery

DELMER provides equipment and process solutions for recovering precious metals from suitable secondary materials, including selected electronic waste and jewellery-related residues. Feed characterization is essential before selecting the recovery process.

Assay & Analysis Laboratories

Accurate precious-metal analysis supports refinery control, incoming-material evaluation and production quality assurance. DELMER supplies fire assay laboratory equipment and complete assay laboratory solutions for gold, silver and other precious metals.

Precious Metal Plating & Galvanic Equipment

Precious-metal plating deposits a controlled metal coating onto a suitable substrate using an electrochemical process. DELMER can provide galvanic and precious-metal plating equipment for industrial applications, with configuration based on substrate, coating metal, bath chemistry, production volume and required finish.

How to Select a Refining System

The appropriate system depends on the metal to be recovered, feed composition, feed purity, batch size, required throughput, target purity, process method, available utilities, ventilation and local safety requirements. DELMER can help evaluate the application and recommend an appropriate equipment configuration.
