The extraction of metals from ore at a mining plant requires the routine analysis of various samples, which include the feed (crushed ore), the tails (waste ore after processing) and the concentrate (final product). In this work, reference materials were analyzed for copper (Cu), iron (Fe), silver (Ag) and arsenic (As) using the Avio® 220 Max hybrid simultaneous ICP-OES, ideal for laboratories looking to improve productivity for analyses usually performed with flame atomic absorption spectroscopy, which can only measure one element at a time.
