Metallurgical Testing Lab at IRT

Having an on-site metallurgical lab gives you fast, accurate and reliable results for electronics analysis. Instead of outsourcing our testing, it allows the IRT team to sample, assay, refine and settle your individual lots of circuit boards in under 45 days. It also reduces cost and risk, allowing IRT to offer fiercely competitive cash pricing on your electronic materials.

Fire assaying is the industry standard process for obtaining gold and platinum data for electronic waste. At IRT, we create the most homogenous sample possible, ending with a powder that is less than 100 mesh (-100 mesh, or <149 microns).

At our metallurgical testing lab, IRT’s certified chemists perform a fire assay and cupellation to extract the precious metals. After a total weight has been documented, the precious metal is digested in acids to extract the gold from the other metals.


IRT will purchase and assay these materials:

  • Gold and silver jewelry
  • AG flake
  • AG bars
  • AU bars
  • Silver solder
  • Sterling silver
  • X-ray film
  • Litho film
  • Other precious metal bearing materials
