About silver-bearing scrap
The industrial sources we see most are switchgear and relay contacts, silver brazing alloy offcuts from HVAC and fabrication work, silver-plated bus connections, and recovery material from photographic or plating operations. In every case the silver is a small fraction of what you are holding: a kilogram of contacts might carry a few tens of grams of recoverable silver, and the honest way to buy it is against an assessment, not a per-kilogram board rate.
Because of that, silver-bearing lots follow a different intake path. We weigh the material with you, describe how the silver content will be assessed, and for larger consignments arrange an assay through a refiner before a final figure is agreed. Nothing is melted or altered before you have accepted the number.
Two limits are worth stating plainly. We buy industrial and process silver scrap, not hallmarked jewellery or bullion — that trade needs a jeweller or licensed assayer, and we will point you there instead. And for every precious-metal purchase we record seller identity and ask how the material was obtained; for anything sold on behalf of a company we need a works order or authorisation letter.
