Most burnable precious metals – such as resins, filters, jeweler’s sweeps, wipes & jars, catalysts, and sludges – are extremely valuable, but also extremely sensitive to losses during the thermal reduction process. Meticulous engineering and customization of the furnaces is critical to optimizing outcomes and precious metal values.
These factors are why Metallix’ Thermal Reduction department offers unmatched expertise in addition to the most advanced equipment in the market.
Metallix’ internal review board assesses every burnable precious material that comes through our department’s doors. Analyzing the physical characteristics, volatility, and safety data of each lot, the board draws up ideal atmospheric conditions designed to reduce the possibility of precious metals losses while increasing outcomes and control.
Higher-combustion scrap is reduced using Metallix’s APR³, an oxygen-starved furnace specifically designed for the most vulnerable precious metals.
As materials travel through APR³, the furnace thermally reduces the organics surrounding the precious metals by way of radiant heat. It is a turbulent-free environment that minimizes precious metals losses.
Other materials enter our oxygen-rich box atmosphere furnaces, our TR1 and TR2 technology, where they’re processed at a rate far slower than industry norms, for finer control. Again, thermal reduction conditions are customized and fine-tuned according to formulas designed specifically for each supplier’s materials. By adjusting temperature, cooling time, and airflow, conditions are optimized – as are precious metal values.
As the APR3 and TR 1 & 2 furnaces thermally reduce precious metals materials; gases and some particulate rise into the pollution control process. These particles flow into the afterburner where the majority are either neutralized or destroyed by its high temperature. The remaining gases and particulate next flow into the wet scrubber system for further neutralization and capture, cleaning the air stream to regulated permissible levels before emitting the air into the atmosphere.

In regard to thermal reduction technology and equipment, Metallix does not view burnable precious metal scrap with a “one size fits all” mentality. By having multiple furnaces, each with different processing specialties, Metallix offers a customized and flexible processing technique for every burnable precious metal scrap material generated, resulting in maximum efficiency and precious metal value.
