Copper Ores
Native copper occurs at the surface of ore bodies and sometimes deeper in the ore body. Some of the compounds formed in the oxidation zone are water soluble. Rain leaches this stuff to below the groundwater level, where it precipitates again, thus enriching the ore concentration at this level. Deep in the ground where reducing conditions ...

The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various loions in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then ...

Iron oxide coppergold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features: (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) abundant magnetite and/or hematite, (4) Fe oxides with Fe/Ti greater than those in most igneous rocks, and (5) no clear spatial associations ...
Cuprite | mineral | Britannica
Cuprite, soft, heavy, red oxide mineral (Cu2O) that is an important ore of copper. A secondary mineral often formed by the weathering of copper sulfide minerals, cuprite is widespread as brilliant crystals, grains, or earthy masses in the oxidized zone of copper lodes. Deposits have been found at
Copper Statistics and Information
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of lowgrade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper .
Copper (Cu) Recycling
The sulfide ores are sent to a concentrating stage while oxide ores are moved to leaching tanks. In the concentrating stage, the minerals are made into slurry (with about 15% copper) and waste slag is removed. If the tailings contain any copper oxide it is sent to the leaching tanks.
