XRF Analysis
XRF Analysis (X-Ray Fluorescence Analysis) is a common testing method used in geology and mining to figure out what materials are in rock samples without damaging them. Think of it like a special camera that can see inside rocks to tell what metals and minerals are there. Companies use this technology because it's quick, accurate, and can be done right at the mining site or in a lab. It's similar to other testing methods like ICP or Mass Spectrometry, but XRF is preferred because it's faster and doesn't destroy the sample. When you see this on a resume, it means the person knows how to operate XRF equipment and interpret the results, which is valuable for mining companies, environmental firms, and geological survey organizations.
