and/or flotation will probably be required for effective recoveries. The largest and most economically attractive pond contained 1,090,000 tons of tailings grading 7 percent barite, or 87,800 tons of the mineral. Metallurgical recovery of the plant was probably about 70 percent from crude ore averaging around 70 percent barite.

Currently, flotation is one of the commonly used method to concentrate barite from real ore, and the fatty acids are the widely-used anionic collectors in the flotation of barite and other oxidized minerals because of the strong interaction occurred between fatty acids and barium/metal site at minerals surface [[6], [7], [8], [9]].

The barite mineral processing plant can also have a water circulation system to avoid waste. The general process of barite beneficiation includes crushing, grinding, screening, gravity separation, flotation and drying. According to the actual ore type, sometimes washing and magnetic separation processes are also included.

Barite is a mineral composed of barium sulfate (BaSO 4 ). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and ...

Moreover, research on RE flotation has rarely considered the use of dissolved sulfate minerals (barite supernatant) as a flotation medium. For example, Ca 2+ is commonly present in flotation pulp and inhibits the flotation of bastnaesite and monazite when using benzohydroxamate as the collector [19].
