Malachite

Main Elements:

Cu, C, O, H

Chemical Composition:

Cu₂CO₃(OH)₂ (Copper Carbonate Hydroxide)

Density:

3.6-4.0 g/cm³

Compressive Strength:

Variable

Melting Point:

Decomposes

Formation:

Forms in the oxidation zone of copper deposits when copper minerals react with carbon dioxide and water. Often forms botryoidal (grape-like) masses.

Composition:

Composed of copper carbonate hydroxide (Cu₂CO₃(OH)₂), making it an important copper ore.

Types:

• Banded Malachite
