Fire Assay

Fire assay is not only an ancient way of enriching gold and silver, but also an important way of gold and silver analysis. Geology, mines, gold and silver smelters use it as the most reliable analysis method and widely used in production. Many countries have set this method as a national standard method for the determination of gold in gold concentrates, copper concentrates, jewelry gold, and alloy gold. With the development of science and technology, there are more and more new techniques for analyzing gold and silver, and analytical instruments are becoming more and more advanced. Compared with other methods, the fire assay has more operating procedures and requires skills. There are many analysts who try to use other analysis methods instead of fire assay. However, the fire assay method is irreplaceable. For the determination of gold content in high-content gold raw materials or pure gold, its accuracy are inferior to other direct determination methods. In the arbitration analysis of gold and silver content, fire Assay analysis can give convincing results for all parties to the dispute.

This is because the fire assay has many unique advantages that other analytical methods do not have: Wide adaptability. It can adapt to almost all samples, from ore, gold concentrate to alloy gold, the fire assay method can accurately determine gold and silver, including those antimonites that cannot be solved by wet analysis. For the analysis of the main components of pure gold, the fire assay can also obtain satisfactory results. Except for very few samples, this method can be adapted to almost all minerals.
