Seperation Of Barium Oxide From Manganese Ores

low-grade manganese ores, which contain iron oxide, may be upgraded by prereduction and magnetic separation. In this study, ferruginous low-grade manganese orewas prereduced by CO, which converted iron oxide to Fe. 3. O. 4. while manganese oxide was reduced to MnO. Then, the iron-rich component was collected by magnetic separation.

Barium | Ba

Barium | Ba

Barium is a silvery-white metal which exists in nature only in ores containing mixtures of elements. It combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds. Barium compounds are used by the oil and gas industries to make drilling muds. Drilling muds make it easier to drill through rock by keeping the drill bit lubricated.

Chemtrails And Barium Salts

Barium levels found in chemtrail samples were at 6.8 ppm or “more than six times the toxic level set by the EPA.” Barium is toxic to humans and animals and causes a dramatic drop in potassium levels in the body. For this reason (and others), barium is known to considerably increase the frequency of heart attacks in persons 65 years and older.
