HiGrade DPI is a novel analysis tool for placer gold that relies on modern image processing to identify gold particles in a high resolution image. Gold particle count, size and shape are instantly presented in a report. Based on that, the calibrated tool calculates the gold content of the sample in g/t or g/m3
" A game changer for placer miners looking for quick and accurate sample results "
Macon Industries - manufacturing world-class exploration and gold mining equipment
Analyze samples in the field or laboratory. Applicable for pits, trenches, auger or percussion drill samples.
Extract data from representative samples. Replaces counting, mercury amalgamation or fire assaying.
Make sound decisions on the move of heavy equipment to the most prospective locations. HiGrade DPI predicts the gold recovery rates.
Image analysis based, non-destructive placer gold analysis was introduced by Prof. Hermann Wotruba, a globally recognized expert in gold exploration at RWTH Aachen University.
The technology was applied extensively by Dr. Andreas Schiffers while evaluating means of gold recovery as a by-product from sand/gravel operations in Europe.
HiGrade Technik first commercialized DPI with robust, 3D printed sample holders, standardized calibration procedures and fully integrated scanning, image processing and reporting software.
