: Using chemistry, heat (such as fire assaying ), or advanced technologies like X-rays and PhotonAssay™ to measure metal content in ore.
: While "purity" measures the percentage of desired substance relative to impurities, an "assay" specifically determines the total amount or functional activity of that substance within a given sample. Industry Applications assayer
: Performing data analysis to provide reliable estimates of a mine's performance and resource value. : Using chemistry, heat (such as fire assaying
An assayer is a specialized analyst, typically a chemist, who performs tests to determine the quality, composition, and value of various substances, most commonly metals and ores . They play a critical role in the mining industry by validating whether a site is economically viable based on the concentration of minerals found in rock samples.
