Rhodochrosite Mineral and Healing Properties

Manganese also adds strength, toughness, stiffness, wear resistance, and hardness to the steel. In aluminum and antimony, manganese also makes highly ferromagnetic compounds, especially with a little copper. Manganese oxide (MnO) is used in fertilizers and ceramics, and manganese carbonate (MnCO3) is a material used in other manganese compounds.

Its main use is as an ore of manganese, which is a key component of low-cost stainless steel formulations and certain aluminium alloys. Quality banded specimens are often used for decorative stones and jewelry.
