The main component of cassiterite is tin oxide, which is an oxide mineral, often containing trace elements such as iron, niobi, tantalum, titanium and manganese. Cassiterite is a tetragonal crystal system. The crystals are often short columnar, slender columnar or double cone-shaped, and the conical aggregates are block, granular or kidney-shaped; with diamond luster to […]

Hemimorphite is a silicate mineral with zinc as the main component. Nó chứa 53.7% zinc and sometimes contains a small amount of aluminum and iron. It is an important mineral of metallic zinc, and only a few colorless and transparent crystals are used as gems. Hemimorphite belongs to the orthorhombic crystal system, and the crystals […]
Pyrite, the English name Pyrite, comes from Greek and means “spark”, because this mineral emits sparks when hit by hard objects such as steel. Because the surface of pyrite is yellow-brown, it has a strong metallic luster on the crystal surface or polished surface, and is often mistaken for gold, vì vậy nó còn được gọi là […]
The staurolite is a hydrous silicate mineral of aluminum and iron. It belongs to the monoclinic or pseudorhombic crystal system. The crystals are well developed and are short columnar. They usually have a cross with an angle of 90° or an X with an angle of 60°. Shape through the double crystal. The staurolite has […]
Epidote is a kind of hydrous calcium aluminosilicate mineral with island structure. Because its composition often contains various trace elements such as manganese, magie, crom, sodium and potassium, there are many kinds of similar substitutes, such as It is rich in manganese as monedrite, chromium is contained in chromium epidote, and calcium is replaced by […]
