WebChalcopyrite is the most important and major source of copper metal. It is widely spread copper–iron sulfide mineral with chemical formula (CuFeS 2). The color is typically brass to golden-yellow (Fig. 1.15), often tarnished, with greenish-black streak and submetallic luster. The hardness varies between 3.5 and 4.0 on the Mohs scale. The mineral pyrite , or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led t…
