PRICE PER KG
Massive chalcopyrite is a copper-iron sulphide that constitutes the world’s primary copper ore. It is distinguished by its metallic lustre and an intense brass-yellow colour that often develops an iridescent patina when oxidised. As it occurs in a massive form, it forms compact aggregates of high density and opacity, making it an essential mineral in both industrial mining and geological collecting.
