Copper processing Copper processing Ores: 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.

Properties of Copper Ores cals.arizona.edu

Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores. There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. Oxide ores contain oxygen. Sulfide ores contain sulfur. Azurite, malachite, and chrysocolla are a few examples of oxides ores.

Azurite: The blue gem material, ore of copper, and pigment.

Geologic Occurrence. Azurite is a secondary mineral that usually forms when carbon-dioxide-laden waters descend into the Earth and react with subsurface copper ores. The carbonic acid of these waters dissolves small amounts of copper from the ore. The dissolved copper is transported with the water until it reaches a new geochemical environment.

Studies re-examine how major copper deposits form | EARTH

Every year, the world consumes about 20 million tons of copper primarily for construction materials like electrical wiring and water pipes. Most nonrecycled supplies come from porphyry copper deposits (PCDs), which form when hot, metal-bearing fluids percolate up through Earth’s crust. But while geologists have long recognized — and exploited — PCDs, two new studies

Copper ore is piled onto a thick high-density polyethylene liner. Sprinklers are placed in the surface to spray a weak acid solution onto the pile. This dissolves the copper in the ore. The copper bearing solutions are collected and pumped to an extraction plant where an organic extractant removes the copper from solution.
