Eight Material Families
Smelting And Refining By-Products
Material generated through smelting, refining, and related production work can vary widely in size, composition, and metal distribution. The first step is understanding how it should be prepared and sampled.
Examples
- Borax slag
- Furnace linings
- Graphite crucibles
- Jewelry crucibles
- Jewelry slag
- Investment powder
Carbon-Based Materials
Spent carbon and carbon fines are used to capture precious metals in mining and
refining. Their material distribution requires a controlled approach to preparation, sampling, and
evaluation.
Examples
- Spent carbon
- Carbon fines
Dusts, Filters And Residues
Fine particles and residual material can require careful review because physical form, source, and composition all affect the right handling and evaluation path.
Examples
- Baghouse dust
- Pond clean up material
- Polishings
- Sweeps
- Sink wash
- Silver residues
Mechanical Scrap And Process Waste
Operational scrap and process material often require an evaluation of physical form, metal content, and preparation needs before the correct processing route is selected.
Examples
- Lemels
- Live scrap
- Electrolytic mesh
- Spent cathode steel wool
- Mine and mill concentrates
- Alluvial gold
- Gold scrap
Bullion And High-Grade Materials
High-grade and partially refined material still needs an accurate understanding of composition, documentation, and the agreed analysis path before settlement can proceed.
Examples
- Doré gold and silver bullion
- Precipitates
- Silver bullion and anodes
- Brazing alloys
- Bullion containing jewelry or platinum-group metals
Electronic And Technical Scrap
Technical material can contain recoverable precious metals in forms that require a specialized review of composition, physical form, safety, and processing requirements.
Examples
- Electronic scrap
- Silver pastes
- Silver tungsten
- Platinum or rhodium thermocouple wire
- Platinum or palladium points
- Platinum, palladium, or rhodium solutions
Dental And Laboratory Alloys
Dental and laboratory material can contain platinum-group metals or other valuable
alloys. The team begins by reviewing the material type and the most appropriate evaluation path.
Examples
- Dental scrap alloys containing gold or palladium
- Platinum crucibles
- Platinum or palladium powders
Silver Compounds
Silver compounds require careful handling, clear identification, and a material specific review before the appropriate recovery path can be determined.
Examples
- Silver chloride
- Silver bromide
- Silver oxide
- Silver solder
- 925 silver scrap
- The Right Path for the Material
The Process Begins With The Material In Front OF Us.
There is no one-size-fits-all route for mining by-products. Physical form, metal distribution, moisture, composition, and documentation all help determine the right preparation, sampling, analysis, and processing path.
Physical Form
Granulated, pelletized, solid, fine, mixed, and high-moisture material may require different preparation before representative sampling can begin.
Material Composition
The material’s expected metals and other elements help guide the appropriate analysis and process discussion.
Documentation And Origin
Material must meet applicable content, origin, ownership, and compliance requirements before work proceeds.
- Material Review
Start With What You Know.
If your material does not fit a standard category, or if you are unsure how to describe it, start with the information you have. Share the material type, available specifications, approximate volume, and any relevant assay information. Our team can help identify the most practical next step before you commit to shipping.

Questions About Materials We Process.
Do you process every type of precious-metal-bearing material?
Just Refiners reviews a broad range of precious-metal-bearing materials, but not every lot follows the same path or meets the same requirements. Material type, content, documentation, origin, ownership, and compliance considerations are reviewed before a process is confirmed.
What if I am not sure which category fits my material?
Start with the information you have. Share a description of the material, available specifications or assays, approximate volume, and any relevant handling notes. The team can help identify the closest material category and the most practical next step.
Can you review material before I ship it?
Yes. A conversation with the team before shipping helps clarify the material, available information, and the process path that may apply. The review does not replace final material, documentation, or compliance requirements.
What information should I have ready?
It is helpful to have a practical description of the material, its source, approximate volume, location, available assays or specifications, and any known handling considerations. If some of this information is unavailable, the team can explain what may be needed next.
Do different materials follow different processes?
Yes. Physical form, composition, moisture, metal distribution, documentation, and process requirements can all affect how material is prepared, sampled, analyzed, and processed. Visit Our Processes to learn more about the available process paths.
