Metallic Deposits Metals occur in all kinds of rocks but usually in concentrations that are too low to be mined. Metallic ore deposits, however, are relatively rare concentrations of metal‐bearing minerals (usually sulfides) that contain enough metal to be profitably mined.
Ore Forming Minerals: Metallic & Non-Metallic Minerals . Certain kinds of mineral can be treated for metal extraction more easily than others; these are commonly referred to as ore minerals. Quite often, different minerals containing a particular metal occur together in a deposit, and are referred to as ore forming minerals.
The terms ore mineral and mineral deposit were originally applied only to minerals and deposits from which metals are recovered, but present usage includes a few nonmetallic minerals, such as barite and fluorite, that are found in the same kinds of deposit as metallic minerals.
