· Most copper is refined from sulphide ores. The process includes the following stages: The copper ores are mechanically crushed and ground. The resulting mixture is treated using flotation with air injection and agitation to leave concentrates containing around 30% copper.

The copper ore become molten copper droplets that fall to the bottom of the furnace forming a molten copper layer with a slag floating on top of it. The molten copper is tapped and sent through the same processes as the reverb smelted copper, except for the converter stage, as it has been already converted to blister copper in the flash furnace.

The production 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 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.

Heap leaching is an industrial mining used to extract precious metals, , uranium, and other compounds from using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places on a liner, then adds the chemicals via drip systems to the ...
