The secondary minerals include limonite, copper greens, azurite. An integrated energy dispersive analyzer (EDS) was used to determine the composition of the secondary minerals formed in the pore space of the material.
Copper Mineral Uses and Properties
Native copper is an element and a mineral. It is found in the oxidized zones of copper deposits; in hydrothermal veins; in the cavities of basalt that have been in contact with hydrothermal solutions; and as pore fillings and replacements in conglomerates that have been in contact with hydrothermal solutions.

CORNETITE (Copper Phosphate Hydroxide) Cornetite is a rare secondary copper mineral that is noted for its deep blue, green blue to green color.It is found in highly weathered, oxidation zones of copper sulfide ore bodies. It has a good deep color, nice crystal forms and an attractive sparkle, all the ingredients for a popular collection mineral.
Copper Ore Types Sulfides vs. Oxides Investing News Network
Copper Ore Types Sulfides vs. Oxides. Both ore types can be economically mined, though they are processed in different ways. Copper sulfide ores are typically the most profitable copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted minerals. However, copper oxide ores are more abundant.
Chalcopyrite Mineral Uses and Properties Geology
Geologic Occurrence of Chalcopyrite. Associated ore minerals include pyrite, sphalerite, bornite, galena, and chalcocite. Chalcopyrite serves as the copper source for many secondary mineral deposits. Copper is removed from chalcopyrite by weathering or solution, transported a short distance, then redeposited as secondary sulfide, oxide,

Geology of Porphyry Copper Deposits
Porphyry deposits and IOCGs are the worlds primary source of copper and they account for more than 60% of the copper production globally but in addition to copper they also supply 100% of the worlds molybdenum production, 10 to 15% of global uranium production and a significant proportion of the worlds gold production in short they make up a

The mineral is associated with chalcocite in zones of secondary enrichment (supergene) of copper sulfide deposits. Commonly found with and as coatings on chalcocite, chalcopyrite, bornite, enargite, pyrite, and other sulfides, it often occurs as pseudomorphic replacements after other minerals.

- In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering. The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements. Supergene enrichment occurs at the base of the oxidized portion of an ore deposit. Metals that have been leache">

An extraordinary assemblage of rare secondary copper minerals was recovered from the Great Australia mine lining and filling vugs in cuprite (Wallace and Pring 1990; Beyer and Day 1995; Sharpe and Williams 1999; Hibbs et al. 2003). The setting is rather like that of similar mineralization at Bisbee, Arizona (Graeme 1981, 1993).
