Origin of a barite-sulfide ore deposit in the Mykonos intrusion

The Mykonos barite veins were exploited by the Mykobar Mining Co until 1984, and yielded ~ 2 Mt of ore. Previous studies of the Mykonos barite-ores have focused mainly on the geology (i.e., lithostratigraphy, Vogeadis, 1961), tectonic framework (i.e., the syntectonic and extensional setting of the mineralization, Menant et al., 2013), and ore ...

The Fascinating World of Barite: From Mining to Everyday …

How is Barite Mined? Barite mining typically involves two main methods: surface (open-pit) mining and underground mining. The choice of method depends on the depth and location of the ore deposits. Surface Mining (Open-Pit Mining) When barite deposits are close to the surface, open-pit mining is the preferred method.
