It was discovered by Ernst Friedrich Glocker in 1847, who named it based on the Greek word “sphaleros” meaning deceiving or treacherous because its lustrous dark crystals can be misguided for other minerals. Siderite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series. All members of the calcite group crystallize in the trigonal system, and have perfect rhombohedral ...

Pyrite is harder than sphalerite, with a Mohs hardness of 6 to 6.5 compared to sphalerite’s Mohs hardness of 3.5 to 4. Pyrite also has a higher specific gravity than sphalerite, meaning it is denser and heavier. Using pyrite and sphalerite interchangeably can lead to serious consequences in certain applications.

Its color is usually yellow, brown, or gray to gray-black The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching. It is a very simple but inexact comparative test. Perhaps its simplicity has enabled it to become the most widely used hardness test. Since the Mohs Scale was developed in 1812, many different hardness tests have been invented.Hemimorphite most frequently occurs as the product of the oxidation of the upper parts of sphalerite bearing ore bodies, accompanied by other secondary minerals which form the so-called iron cap or gossan.
