Malachite often results from the [[Supergene (geology)|supergene]] weathering and oxidation of [[Hypogene|primary]] [[Sulfide mineral|sulfidic]] [[List of copper ores|copper]] [[ore]]s, and is often found with [[azurite]] (Cu<sub>3</sub>(CO<sub>3</sub>)<sub>2</sub>(OH)<sub>2</sub>), [[goethite]], and [[calcite]]. Except for its vibrant green color, the properties of malachite are similar to those of azurite and aggregates of the two minerals occur frequently. Malachite is more common than [[azurite]] and is typically associated with copper deposits around [[limestone]]s, the source of the carbonate.

Large quantities of malachite have been mined in the [[Urals]], [[Russia]]. Ural malachite is not being mined at present,<ref>[http://gazeta.aif.ru/_/online/aif/1334/46_02 Куда делись символы России?] {{Webarchive|url=https://web.archive.org/web/20131202231359/http://gazeta.aif.ru/_/online/aif/1334/46_02 |date=2013-12-02}} [[Argumenty i Fakty]] (24 May 2006)</ref> but G.N Vertushkova reports the possible discovery of new deposits of malachite in the Urals.<ref>Somin, L.
