Chlorargyrite is a mineral that is also known as cerargyrite or horn silver. The term chlorargyrite is derived from the Greek words χλωρός (chlōrós) which means green, and ἄργυρος (árgyros) which means silver. This mineral is a secondary silver mineral that is found in the oxidized zones of silver veins. Chlorargyrite is a relatively uncommon mineral, but it is important in the mining industry because it is a major source of silver. Other synonyms for chlorargyrite include silver chloride, argentite, and cerargyrite. These synonyms are commonly used in the scientific and mining communities to refer to this mineral.
