Phosphosiderite


Phosphosiderite is a rare mineral named for its main components, phosphate and iron. The siderite at the end of phosphosiderite comes from "sideros", the Greek word for iron. It was discovered in 1890. It is mined in some parts of Chile, Argentina, Germany, Portugal, and the United States. It is totally soluble in hydrochloric acid and nearly insoluble in nitric acid.
