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 percent to ...

The mining process is done in three stages. First, holes are drilled and loaded with explosives that are set off, and the ore breaks apart. Second, the loosened ore is now mucked or scooped and put into special underground haul trucks. Each truck delivers roughly 100,000 pounds of ore to the surface.

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 9799%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

A stamp mill consists of a set of heavy steel ( iron shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is ...

Milling. Once the copper ore has been mined, it must be milled to separate the copper from the rest of the rock. This is done via crushing and grinding. Concentrating. The next step in copper production is concentrating. This process involves adding chemicals to the milled ore to separate the copper from the rest of the metals present. Smelting
