Its compounds dey commonly seen as copper(II) salts, wey often dey give blue or green colors to minerals like azurite, malachite and turquoise and dem don dey widely use historically as pigments. Architectural structures wey dem build with copper dey corrode to give green verdigris (or patina). Decorative art dey prominently feature copper, both by itself and in di form of pigments.

Copper dey occur naturally as native copper and e don dey known to some of di oldest civilizations wey dey recorded. E get history of use wey dey at least 10,000 years old, and estimates of how e take dey discovered dey place am for 9000 BC for di Middle East; dem find copper pendant for northern Iraq wey date back to 8700 BC. There dey evidence say gold and meteoric iron (but not iron smelting) na di only metals wey humans dey use before copper. Di history of copper metallurgy dey thought to follow dis sequence: 1) cold working of native copper, 2) annealing, 3) smelting, and 4) di lost wax method. For southeastern Anatolia, all dis four metallurgical techniques dey appear more or less simultaneously at di beginning of di Neolithic around 7500 BC. However, just as agriculture dey independently invented for several parts of di world, copper smelting dey invented locally for several different places. E probably dey discovered independently for China before 2800 BC, for Central America perhaps around 600 AD, and for West Africa around di 9th or 10th century AD. Investment casting dey invented for 4500–4000 BC for Southeast Asia and carbon dating don establish mining for Alderley Edge for Cheshire, UK for 2280 to 1890 BC. Ötzi di Iceman, a male wey dem date from 3300–3200 BC, dey found with an axe wey get copper head wey 99.7% pure; high levels of arsenic for im hair suggest say e dey involved for copper smelting. Experience with copper don help for di development of other metals; in particular, copper smelting lead to di discovery of iron smelting. Production for di Old Copper Complex for Michigan and Wisconsin dey date between 6000 and 3000 BC. Natural bronze, a type of copper wey dem make from ores wey dey rich in silicon, arsenic, and (rarely) tin, come into general use for di Balkans around 5500 BC.[citation needed]

Now, provide a numbered list of answers to these questions:

1. Copper dey occur naturally?
2. How long e don dey used?
3. When e dey discovered?
4. Where?
5. Wetin dem find for North Iraq?
6. Wetin e dey date?
7. Wetin be di metals wey people dey use before copper?
8. How many sequences copper metallurgy get?
9. Wetin happen for 2800 BC?
10. Where copper dey mined for di roman era?
11. Wetin color copper dey turn for architecture?
