According to my chemistry book it's copper carbonate.
When malachite is heated, it decomposes to form two main chemicals: copper(II) oxide (CuO) and carbon dioxide (CO2). This reaction occurs because the heat causes the malachite to lose its water content and break down into these two substances.
If copper appears in the name of a compound, it indicates that the compound contains copper as one of its constituent elements. The presence of "copper" in the compound's name signifies the inclusion of copper atoms within the chemical structure of the compound.
When malachite (copper carbonate) reacts with hydrochloric acid (HCl), carbon dioxide gas (CO2) is released.
copper oxide
Copper sulphate.
The compound Cu2OH2CO3 is commonly known as malachite. It is a green mineral that consists of copper(II) hydroxide carbonate and is often used as a copper ore and in jewelry. Malachite is notable for its vibrant color and banded appearance.
The mineral malachite is an ore of copper.

The basic copper carbonate is known in mineralogy as malachite or azurite.
copper oxide
Copper sulphate.
The formula Co3Cu represents a compound of cobalt and copper. The name of this compound would be tricobalt copper.
Copper (I) bromide. Unlike with a zinc compound question I just answered, the (I) here is pretty important; both copper (I) bromide and copper (II) bromide exist and are commercially available.
The compound containing copper and sulfur is called copper(II) sulfide.
Copper Iodite
