When mining for precious metals, ores are extracted from the ground and subjected to various sample preparation procedures in order to remove the metals of interest. A commonly used procedure to isolate metals from the ore is fire-assay, which leaves a matrix-free “button” of the metal. This work focuses on the analysis of precious metals in simulated digested precious metal buttons, and demonstrates the ability of the PinAAcle™ 500 Flame AA spectrometer to accurately measure low-level gold, palladium, platinum, copper, and silver in matrices which result from the fire-assay preparation of ore samples.
