Precious Metal Refining
Our precious metals team specializes in extracting high-value precious metals from complex manufacturing scrap—turning production waste into profit.
Whether you’re working with circuit boards, semiconductors, or gold-plated connectors, our advanced recovery processes unlock residual value others miss.
Utilizing state-of-the-art separation techniques, we recover gold, silver, platinum, palladium, and other valuable metals from a variety of materials with unparalleled efficiency and accuracy. Those materials include:
- Solutions
- Burnables
- Residues
- Sludges
- Dusts and Powders
- Production Scrap
We Offer 5 Routes to Revenue
Chopping (Mechanical Reduction)
Mechanical reduction is effective for size reduction for electronics, printed circuit boards, assemblies and components. Size
reduction allows us to collect a homogeneous sample to determine material value.
Roasting (Thermal Oxidation)
Roasting is used for wet materials and material containing organics, including sludges, residues and burnables. We are equipped
with high-capacity natural gas-fired ovens to process large volumes of materials. Our ovens are equipped with afterburners and a
baghouse for pollution control and oven efficiency. The roasting process burns off many impurities and produces dry material
suitable for sampling or additional processing.
Milling
Dry crushable materials are milled, enabling us to take a representative sample from our rotary sampler to determine precious
metal content. We utilize vibratory and vertical ball mills.
Chemical Processing (Solutions Plating and Metal Stripping)
Typically, plating and stripping solutions will be plated out to extract precious metals from the solution. Plated parts can be
submerged in a chemical bath to recover precious metals from the parts. Our chemical processing includes cyanide stripping.
Melting
We operate ten natural gas-fired furnaces with graphite crucibles to produce precious metal bullion. Alloying precious metals
with copper ensures melt homogeneity and accurate sampling results.
