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.

Jewellery filing and setting table with built-in dust collection that recovers the precious gold and silver dust generated during filing and setting work. A practical everyday workstation for jewellery manufacturing workshops that want to cut metal loss right at the bench.

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.

Compact air purifier that captures the fine, respirable dust released during jewellery laser operations, protecting operators and keeping workshop air clean.
