extraction of copper from malachite

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 spaces, deep underground, where the water table and hydrothermal fluids provide the means for chemical .
