GOLD RECOVERY AND REFINING SYSTEMS FOR THE JEWELRY INDUSTRY

Incineration of Waste into Ash

Waste is incinerated using a furnace equipped with a flue gas treatment system that complies with environmental standards, producing gold-bearing ash for subsequent recovery.

Advantages

  • Flue gas emissions are treated to comply with Vietnamese environmental standards.
  • Organic materials are completely burned, resulting in clean white ash.
  • Electric heating system ensures safe operation while reducing energy consumption.

Gold Recovery from Ash

Ash is processed in a high-temperature melting furnace, where combustible metals are completely burned off and the gold is melted into an alloy ingot, allowing it to be separated from non-metallic impurities.

Features

  • Gas-fired furnace capable of reaching temperatures up to 1,600°C.
  • Uses a special lead-free, non-toxic flux.
  • Gold recovery efficiency exceeds 94%, outperforming traditional recovery methods.
  • No lead blowing process required.

Practical Applications

  • Treatment of Rhodium plating wastewater.
  • Recovery of Rhodium (Rh) from solutions generated during polishing, rinsing, and finishing processes.
  • Recovery of Rhodium (Rh) from filter sludge, oxides, and precious metal residues.
  • Suitable for high-end electroplating lines, jewelry manufacturing, and industrial component production.
  • Optimizes raw material costs in electroplating, refining, and precious metal recovery operations.

High-End Jewelry Electroplating Workshops

  • Suitable for white gold, silver, and platinum electroplating lines.
  • Optimizes rhodium consumption and minimizes plating losses.
  • Recovers high-purity rhodium for direct reuse in production.
  • Enhances jewelry surface quality with a brighter finish and consistent coating adhesion.

Industrial Wastewater Treatment Facilities

  • Removes residual Rhodium from wastewater, ensuring the treated effluent meets discharge standards.
  • The recovery system transforms “waste” into a high-value resource.
  • Reduces operating costs and the cost of treating sludge containing heavy metals.
  • Easily integrates into existing wastewater treatment systems.

Precious Metal Manufacturing & Refining Plants

  • Maximize the recovery of Rhodium from sludge, waste solutions, and rinse water.
  • Ensure high-purity rhodium that can be easily recycled and fed back into the refining process.
  • Reduce dependence on imported rhodium, whose market price is highly volatile.
  • Support ESG compliance and improve the company’s environmental performance rating.

Businesses Seeking to Optimize Precious Metal Costs

  • Recover rhodium losses throughout the entire production process.
  • Monitor and control precious metal consumption in real time.
  • Optimize raw material costs, especially as rhodium remains the most valuable metal in the Platinum Group Metals (PGM).
  • Improve production efficiency without modifying existing production lines.
