The best known copper carbonates are green malachite and the more unstable deep-blue azurite (not to be confused with lapis lazuli). Copper silicates and turquoise – a rare, blue copper aluminium phosphate mineral, prized in itself - may also be present. Native copper occurs at the surface of ore bodies and sometimes deeper in the ore body.

Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content.

Secondary ores, called oxide ores, formed as weather and other natural forces altered ancient rocks. Both types of ore are mined and processed to extract the copper. Primary ore minerals of copper include malachite, azurite, chalcocite, bornite, and cuprite. One of the more familiar and beautiful minor ore minerals of copper is chrysocolla.

A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range of silicate minerals from quartz to talc and clays.

These are secondary minerals, meaning that they formed by alteration of the original copper ore minerals. Now, why are the colors different? In Learn More for specimen #23, we talked about crystal field effects as a cause of color. Copper (Cu) atoms, in both malachite and azurite, are surrounded by 4 oxygen atoms essentially in a rough square.

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

Further, through the use of biooxidation, it is now possible to leach many of the copper sulfide minerals present in the ore. While chalcopyrite remains refractory to ambient temperature bioleaching, other copper sulfide minerals - the secondary sulfide minerals - such as chalcocite, covellite, bornite, etc. - are leachable by today's technology.

Apr 13, 2016 Copper minerals usually occur in low grade deposits and require concentration prior to smelting. The method and degree of concentration depends on smelter location and schedules, together with the nature of the ore deposit. Sulphide copper ores generally occur with pyrite, pyrrhotite, arsenopyrite and molybdenite, and with gold and silver.

Preliminary Model of Porphyry Copper Deposits

Ore minerals occur as disseminations and in stockworks of veins in hydrother-mally altered, shallow intrusive complexes, often porphyritic, and in adjacent country rocks. This model covers all porphyry-style copper deposits and includes copper-molybdenum, copper-molybdenum-gold, and copper-gold subtypes that are some-

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.
