How We Do It

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 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.

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.

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.

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.
