Question: 1) To be considered a mineral commodity, an orebody has to reach an ore concentration of at least the concentration factor (CF). How does copper compare to other commonly mined mineral resources? 2) How does the concentration factor likely related to the costs of production of that ore? Think about the amount of wasted rock (gangue ...

We achieve a concentrated ore with a high percentage of metal by eliminating these impurities. The concentration of ore, also known as ore enrichment, is the process of removing gangue particles from ore in order to enhance the percentage of metal in the ore. The difference in physical or chemical properties of the ore and the …
The compactness (density) of the ore concentrate was found to have very little effect on pXRF readings. The pXRF readings for Fe and Si were comparative to laboratory-based XRF results. Based on the strong correlations between the pXRF and XRF results (Fe: R 2 > 0.99, Si: R 2 > 0.96), linear calibrations were adopted to improve the accuracy of ...
