Fire assaying is the industry standard process for obtaining gold and platinum data. At IRT, we create the most homogenous sample possible ending with a powder that is less than 100 mesh. Using a custom flux, IRT’s certified chemists perform a fire assay and cupellation to extract the exact amount of precious metals. After a total weight has been documented, the precious metal is digested in acids to extract the gold from the other metals.
