Fluoride wastes from mineral industry processing plant . The equilibrium amount of fluoride in solution when 0.50 wt% fluorite was added to the soils was substantially greater when the soils had been previously amended with 0.5 %rt% calcite. Overall it can be concluded that soil and rock forming minerals are able to abstract a

2014. 3. 6. Fluoride processing of natural ilmenite with the use of ammonium hydrogen difluoride (NH4HF2) as an effective fluorinating agent is suggested. Chemistry, composition, structure, thermal and hydrolytic properties of fluorination products were investigated. Ammonium fluoro- and oxofluorotitanates are suitable for preparing of titanium dioxide as pigmentary product or as doped by nitrogen and
Features of plasma processing of fluoride solutions of refractory metals were studied. It was shown that pyrohydrolysis of niobium, tantalum, and titanium fluorides occurs in the gas phase, thus

2021. 1. 20. Fluoride (/ ˈ f l ʊər aɪ d, ˈ f l ɔːr-/) is an inorganic, monatomic anion with the chemical formula F − (also written [F] −), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals
2020. 3. 9. Fluoride is ubiquitously present throughout the world. It is released from minerals, magmatic gas, and industrial processing, and travels in the atmosphere and water. Exposure to low concentrations of fluoride increases overall oral health. Consequently, many countries add fluoride to their public water supply at 0.7–1.5 ppm.
