Geoscan Elemental Analyzer for optimising plant feed quality and process performance


Geoscan (using PGNAA) is used for multi-elemental analysis of conveyed bulk materials in real time measuring continuously through the full bed depth, and unaffected by belt speed, particle size, layering and dust levels. Tonnage weighted results are used to monitor quality, divert increments (bulk sorting), ore blending, and feed forward control to optimize downstream processes. Advance warning of compositional variability enables appropriate and timely reactions prior to processing. This may include modifying feed rate, changing feed blend, or modifying the treatment regime in anticipation of a change in feed quality or mineralogy. Major benefits have been achieved at existing operations.
