Refining & Assaying

Acid hood cabinets with fume scrubbers in single and double station configurations, protecting gold refining operators from toxic acid fumes, vapours and dust.

Controlled-atmosphere annealing furnace for the gold chain and jewellery industry. The protective atmosphere prevents oxidation during annealing, so chains and components come out bright and scale-free every cycle — built to your specifications.

Continuous belt soldering furnace with controlled atmosphere for the gold chain industry. Chains travel through on a conveyor belt for uniform, oxidation-free soldering at production scale — built to your specifications.

Dissolving plant that removes copper and iron from precious metal scrap before refining, improving the purity and speed of downstream gold and silver recovery. An eco-friendly system from an end-to-end precious metal refining range, backed by dependable after-sales service.

Electrically heated cupellation furnace for fire assaying of gold and silver, holding up to 36/24 assay samples at a time. Digital control with LED display maintains working temperatures up to 1200°C on a standard single-phase supply — an essential furnace for hallmarking centres and assay laboratories. Features: • Electrically heated cupellation furnace for fire assaying • Max working temperature 1200°C • Digital control with LED display • Holds up to 36 / 24 assay samples at a time • Single phase 220/250 V, 50 Hz

Dust burnout furnace that incinerates the dust and sweeps generated during jewellery manufacturing to recover the precious metal locked inside. Designed and manufactured with supreme quality materials and the latest technology, and available in different sizes and designs to suit your recovery volumes.

Effluent treatment plant (ETP) for treating wastewater from jewellery production and precious metal refining. It handles contaminants including organic and inorganic matter, heavy metals, oil & grease and suspended solids, in batch or continuous flow — available as chemical, biological, combined chemical & biological, or thermal treatment systems.

Graining machine for gold and silver that produces uniform round grains (shots). Make pre-refining shots with a large surface area to cut reaction time and increase refining output, or turn final refined metal into clean, beautiful grains for alloying and further use.

Fire-assay based precious metal analyzers for hallmarking centres and assay laboratories, in single-sample and six-sample models.

Rotary tumbler gold refining machines in 15, 25 and 50 kg batch capacities, delivering nearly 100% recovery at 999+ purity from carat scrap, filings, polishings, sweepings and dust.

Sedimentation settling tank for jewellery production wastewater that lets suspended particles settle out as water flows slowly through the tank. It recovers the fine precious metal sludge that standard gravity sedimentation tanks and filter presses struggle to catch, so valuable metal is not lost down the drain.

Silver refining machines in SIL 10, 25, 50 and 100 models, complete with fume cabinet, SS reaction kettle, separate precipitation tank and fume scrubber for safe, high-purity silver recovery from scrap.
