The cuprite price for faceted gemstones is $40-$200 per carat. Most cabochons are azurite cuprite, malachite cuprite, or chrysocolla cuprite. These stones go for around $50 to $200 each at wholesale. Chrysocolla and cuprite mixtures are sometimes sold as "Sonora Sunrise" or "Sonora Sunset.".

Cuprite (Cu 2 O) is difficult to directly leach in acidic solutions. In the absence of oxygen, the acidic leaching process of cuprite occurs via a disproportionation reaction and can achieve a maximum cuprite leaching rate of only 50%. Furthermore, to improve the copper leaching rate, Cu(Ι) in cuprite must be oxidized via electrochemical ...

The ore used for extraction is copper pyrites, which is crushed, concentrated and then heated in the presence of air. During heating the …

Cuprite forms in the oxidized, upper portions of copper deposits in association with azurite, malachite, chrysocolla, chalcocite, chalcanthite [hydrous copper sulfate, CuSO. 4 ·5H. 2. O], and native copper. Cuprite alters readily and is sometimes reduced to native copper to form copper-after-cuprite pseudomorphs.
