Geometallurgical approach and quantitative mineralogy of the
copper/gold deposit of Chelopech
1. Location
Chelopech
•Western Bulgaria at 75km from Sofia
•Southern part of BTS belt
•Central position in Panaguyrishte district
4. Classification of minerals
2. Samples
•55 images/ polished section •3 wavelengths/image
•Creation of polished sections (-38µm, 38-75µm and +75µm) from flotation plant samples
3. Acquisition
5. Image correction
•Excellent classification
but
« Mixel » and plucking problems
6. Quantitative results •Allow to know proportions of each mineral in each sample
