EN 15587 Atomic Absorption Analysis of Metals in Minerals Testing
The EN 15587 standard specifies a method for determining the concentration of metals in minerals using atomic absorption spectroscopy (AAS). This method is essential for quality management, compliance officers, and R&D engineers involved in mining operations. The analysis provides precise quantification of trace elements, which are critical to understanding mineral properties and optimizing extraction processes.
The process involves several key steps: sample preparation, digestion, and analysis using an atomic absorption spectrometer equipped with a graphite furnace atomizer for accurate detection. The standard ensures consistency by providing detailed instructions on specimen handling and calibration procedures. This method is particularly useful in the mining sector where accurate metal content analysis can influence decisions regarding ore processing and environmental impact assessments.
The application of EN 15587 goes beyond mere compliance; it also aids in research and development efforts aimed at improving extraction efficiency and reducing waste. By ensuring that metals are accurately quantified, this standard supports the production of high-quality mineral products.
