Barite ore crushing and washing. In the crushing and washing process of barite ore, efficiency is key. If the barite ore contains a large amount of mud, the ore washing machine needs to be added. Commonly used log washers and spiral sand washers use high-pressure water jets to remove the mud and clay attached to the barite ore, making it easier to separate …

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 ...

Salt-roasting minus 10-mesh Calico ore samples before cyanidation increased silver recoveries to 75 to 85 percent. Barite could not be floated from the cyanidation residues in products that met minimum barite specifications. Flotation of the untreated ore recovered 85 to 93 percent of the barite in specification-grade barite concentrates.
