Silver in Barite Ore

13 Jun 2012

In this note the measurement of silver (Ag) as well as iron (Fe), zinc (Zn) and lead (Pb) in barite (BaSO4) concentrates and final tails is demonstrated using the empirical method. The study indicates the EDXRF analyzer is an excellent tool for screening and quantifying silver as well as major and minor elements commonly found in mining and ore material.

X-Ray Diffraction and SpectroscopyX-Ray diffraction & spectroscopy are used in material characterization to discern the structure and elemental composition of a sample. X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography.
