Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 % Cu) must be concentrated by beneficiation.

Copper processing - Ores | Britannica

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 from 0.4 percent to ...

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

Comminution | Multotec

The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials.
