Malachite, Cu2CO3(OH)2(s), is a chemical or pigment that is typically synthesized in solid form, hence understanding its solubility is crucial. it makes sense that it should have an extremely low solubility in water.. A substance's solubility in chemistry refers to its capacity to combine well with another substance—the solvent—to form a solution.

Malachite is composed of copper carbonate hydroxide (Cu2CO3 (OH)2), while pyrite is composed of iron sulfide (FeS2). The crystal structure of malachite is monoclinic, forming elongated prismatic crystals. On the other hand, pyrite has a cubic crystal structure, giving it a distinct geometric shape.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
