Fire Assay is an analytical method for determining the purity and obtaining the metals in their pure form. It is generally feasible for gold and platinum group metals. It is the assaying technique that uses modern methods, but its principle is like the conventional methods.
Fire assay is a vital aspect of determining the precious metal content of samples. There are a number of stages in the process from the original sample to isolated precious materials which can be tested using other techniques. Samples are placed in crucibles and heated to more than 1000°C with other compounds including lead oxide.
Fire Assay. FA Fusion. The appropriate amount of a sample is weighed on an analytical balance, mixed with lead collection flux to a homogeneous state (uniform colour) and loaded into a fusion furnace at 1150 o C for 50 minutes.
Fire Assay or Lead Collection Fire Assay remains the method of choice for quantitative gold determination. The fore assay flux mixture has been carefully formulated to optimise precious metal recovery in diverse mineralogical matrices. Aqua Regia will digest many minerals, however, silicates and refractory minerals will remain largely undigested.
FIRE ASSAY. Fire assay is the industry standard process for obtaining gold and platinum group element (PGE) concentrations from high-grade ores. Lead collection gold fire assay is considered the most definitive technique for gold analysis although precious metals can also be determined by this procedure.
