What is Enargite?

Minerals are solid substances, occurring naturally. Minerals are not organic compounds as their origins are inorganic. Interestingly, the process of formation of minerals do result from organic processes. What is Enargite? Here you can know all about it. Enargite mineral belongs to Sulfide mineral. You can know more about the Physical Properties of Enargite and find out all the aspects pertaining to the appearance and form of a mineral. It is also important to know the IMA status of a mineral, for this mineral IMA status is Valid Species (Pre-IMA) 1850. Another important aspect is the minerals strength or hardness, Enargite has Mohs Hardness between 3.
