Basic copper carbonate, also known as copper carbonate, is malachite green, so it is also called malachite. It is a precious mineral gem. It is a substance produced by the reaction of copper with oxygen, carbon dioxide and water in the air. It is also known as copper rust and its color is green. Heating in air will decompose into copper oxide, water and carbon dioxide. Dissolve in acid and form corresponding copper salt. It also dissolves in cyanide, ammonium salt and alkali metal carbonate aqueous solution to form copper complex. When boiled in water or heated in strong alkali solution, brown copper oxide can be formed and decomposed into black copper oxide at 200 ℃. It is unstable in hydrogen sulfide atmosphere and can react with hydrogen sulfide to form copper sulfide. Existuje viac ako desať foriem zlúčenín v základnom uhličitane medi podľa pomeru CUCO3: H2O. It exists in the form of malachite in nature.

If it is placed in the air for a long time, it will absorb moisture and release carbon dioxide, and slowly turn into green malachite. It exists in the form of azurite in nature. Copper carbonate and copper bicarbonate do not actually exist. Základné zrážanie uhličitanu meďnatého sa môže získať pridaním uhličitanu sodného na zriedenie roztoku síranu meďnatého alebo prechádzajúcim oxidom uhličitého do suspenzie hydroxidu medi. Basic copper carbonate can be regarded as composed of copper hydroxide and copper carbonate. In fact, there are two kinds of copper carbonate: one copper hydroxide and two copper carbonate.
The chemical formula of the former is cuco3 · Cu (OH) 2, which is a grass green monoclinic crystalline fibrous mass or dark green powder. The precipitate obtained from the solution initially appears green and turns dark green in the solution after placement. Je toxický a je hlavnou zložkou zelenej hrdze (bežne známa ako meďná zelená) tvorená na povrchu medi.

Chemický vzorec z druhého z nich je 2Cuco3 · Cu (OH) 2, tmavá obloha modrá, veľmi jasné monoklinické kryštály alebo kompaktné kryštalické zhluky. It is insoluble in water, soluble in ammonia and hot and concentrated sodium bicarbonate solution to form blue, which decomposes at 300 ℃. Na výrobu signálnych bômb, ohňostrojov, pigmentov farieb, iných solí medi, aktivátorov tuhých fosforu, insekticídov, ošetrenia semien, baktericídov, baktericídov a antidotov, ako aj elektroplaty sa môže použiť
