Frequently asked questions
FAQs for the Fire Assay Muffle Chamber
What is Fire Assay and why is it used?
Fire Assay is a highly accurate laboratory method used to determine the precious metal content in ores, concentrates, and geological samples. The process uses high temperatures to separate gold, silver, platinum group metals, and other valuable elements from surrounding material. Because of its precision and reliability, Fire Assay is considered the industry standard for precious metal analysis worldwide.
How does the Fire Assay process work?
The sample is first mixed with special fluxes and heated in a furnace at very high temperatures. During melting, precious metals collect into a lead or nickel button while unwanted material forms slag. The metal button is then separated and further refined to accurately measure the precious metal content. This process delivers highly reliable results, even at very low concentrations.
