Ochsit

Ochsit is a rare mineral form of manganese ore that crystallizes in the trapezohedral crystal system. It is a manganese hydride mineral with the chemical formula Mn(HCOO)·H2O. Ochsit is typically found in sedimentary deposits, particularly in the oxidized zones of manganese rich hydrothermal veins. The mineral has a pale yellow or orange color and exhibits a vitreous luster. It is relatively soft, with a Mohs hardness of about 4, and is soluble in water.

Ochsit was first described in 1883 by a German geologist. The mineral is relatively rare, and most known deposits are found in Europe, Asia, and North America. Notably, significant deposits of ochsit have been discovered in the Jáchymov District of the Czech Republic, the Erongo Mountains of Namibia, and in the Tri-State District, which spans across western Kansas, eastern Colorado, and southwestern Missouri, in the United States.

Ochsit has limited industrial use, primarily in the production of manganese, a key component in the production of steel and other alloys. Ochsit's hydride content can make it a somewhat reactive mineral, which may affect its potential uses and applications. From a collector's perspective, ochsit is prized for its relatively rare occurrence, distinctive color, and limited availability.

The name "ochsit" is thought to come from the Greek language, likely derived from the word "ochra," meaning "manganese oxide."
