Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO 3.At ambient temperatures, it is an ionic solid (a salt) consisting of copper(II) cations Cu 2+
Basic copper carbonate is used to remove thiols and hydrogen sulfide from some gas streams, a process called "sweetening". Like many other copper compounds, it also has been used as an algaecide, wood preservative and similar applications. It is a precursor to various catalysts and copper soaps. [3]
Copper carbonate may refer to : . Copper (II) compounds and minerals. Copper(II) carbonate proper, CuCO 3 (neutral copper carbonate): a rarely seen moisture-sensitive compound. ...
Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.

Like aluminium, copper is recyclable without any loss of quality, both from raw state and from manufactured products. [45] An estimated 80% of all copper ever mined is still in use today. [46] In volume, copper is the third most recycled metal after iron and aluminium. [47] As of 2023, recycled copper supplies about one-third of global demand.
Tarnish does not always result from the sole effects of oxygen in the air. For example, silver needs hydrogen sulfide to tarnish, although it may tarnish with oxygen over time. It often appears as a dull, gray or black film or coating over metal. Tarnish is a surface phenomenon that is self-limiting, unlike rust. Only the top few layers of the ...
