2021-4-12 Those hard rock minerals can easily be determined with XRD. The related annual savings of a larger mine exceed the costs of an X-ray laboratory by far. (Source: Mining Magazine (March 2015) p 38-40). Properties relevant to extracting Copper from the rock solely depend on the type of minerals present in the specimen and not the chemistry.

2021-2-21 Unfortunately, a lot of rocks look almost identical to copper making it difficult to distinguish the two. However, once you look at a rock that is copper, a little name will pop up saying that it’s copper. You may need to break a few chunks of the copper deposit before it actually drops any copper ore.

The copper ore production process operation as defined in Section 3.1 is simulated for a period of one year with various failure modes. The time evolution of the cumulative cost curves and copper output for 100 Monte Carlo (MC) simulations are shown in Figure 5 for easier visualisation. More MC simulations can be done while characterising the system.

The least common method in hard-rock mining, block caving, is typically saved for low-grade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn.
