Copper processing
Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper in an ore can vary …

Copper Concentrate Enrichment Process
Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.

The process involves copper concentrate, containing about 30% copper, and fluxes like silica (SiO₂) and limestone (CaCO₃) to bind impurities. The furnace operates at high temperatures, typically around 1,200–1,300°C (2,200–2,400°F), melting the concentrate to separate the desired copper minerals from impurities.
