Occurrence, uses, and properties. Native copper is found at many locations as a primary mineral in basaltic lavas and also as reduced from copper compounds, such as sulfides, arsenides, chlorides, and carbonates. (For mineralogical properties of copper, see the table of native elements.) Copper occurs combined in many minerals, such as chalcocite, chalcopyrite, bornite, cuprite, malachite, and

This property is common amongst most dense, finegrained textured rocks, such as basalt. Density. The density of basalt is quite high, which can be seen through the combination of the rocks porosity: – 1%, and its bulk density: – 3 Mg (megagram) per m 3, This is because, around 50 percent of basalt is made of silica.

Copper Copper Principal compounds: Copper forms compounds in the oxidation states +1 and +2 in its normal chemistry, although under special circumstances some compounds of trivalent copper can be prepared. It has been shown that trivalent copper survives no more than a few seconds in an aqueous solution. Copper(I) (cuprous) compounds are all diamagnetic and, with few exceptions, colourless.

Chalcocite, copper(I) sulfide (Cu 2 S), is an important copper ore mineral. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur. It occurs as a secondary mineral in many ore bodies in a zone called the supergene

Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below). The anodes for this process were traditionally leadbased alloys, but newer methods use titanium or stainless steel. The cathode is either a strip of very pure copper which the new copper plates on to, or stainless steel which it has to be removed from later.
