Our Karat Scrap Process

Each container or lot received goes through an extensive checking and sorting process. Materials received are separated, recorded, weighed and pictures are then taken of each lot.

All precious metals are melted in our state of the art induction furnaces. Unlike most refiners who mix karat scrap with simply borax, we, at LGS, have a proprietary flux blend that is designed to extract the most possible gold and to remove the most possible impurities.

Molten metals and flux blends are homogenized inside our induction furnaces. A pin tube sample is taken from each melt. The contents of the crucible are poured into a mold and are allowed to cool naturally.  The bar is then weighed, sampled and recorded. 

The final step in the process is analyzing the samples. The most common analytical process we utilize is a Fire-Assay. We follow strict ASTM guidelines when performing this step to ensure and certify 99.99% accuracy on your results. In addition to other analytical techniques such as chemical analysis, induction coupled plasma (ICP) or atomic absorption spectroscopy (AAS).
