The barite-riche iron ore of the same deposit was treated by anionic flotation using Na-DDS as a collector for floating barium sulfate, and sodium silicate as a depressant for iron minerals (Mossallam, 2004). The feed size fraction for the flotation cell was -250+80 μm assaying 36.5% Fe and 23% BaO. After
The Barite Beneficiation Process is one of flotation, it is used as an ingredient in "heavy mud" for oil-well drilling, for which purpose specifications demand a material meeting the drilling "mud" specifications. Fineness: 98% finished product must pass through 200 mesh. (90-95 % will pass through 325 mesh screen.)
It is rich in color. It is an important fluorine-containing mineral in nature and the main source of fluorine for industrial use. Fluorite often coexists with calcite, dolomite, quartz, barite, pyrite, galena, sphalerite and other minerals, and is similar to calcite, barite and other common gangue minerals, making flotation separation more ...
