what metal does calcite ore become

Malachite Wikipedia

Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 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.

Does carbonate have calcium carbonate in it Answers

No. The carbonate ion contains only carbon and oxygen. Since it is a negative ion, it must combine with some positive ion. If that positive ion is calcium, you get calcium carbonate.
