Recently, high fluorspar prices and overall fluorspar demand made it possible to raise capital to restart mines that were forced to shut down due to low fluorspar prices in early 1990's and to finance development of new fluorspar deposits. World-scale economic slowdown may result in decreased demand for fluorspar and cause corresponding price
Total reported U.S. fluorspar consumption increased by more than 9% in 2004 compared with that of 2003. Consumption of acid grade for HF and AlF 3 increased by 12% to 586,000 t, but consumption of fluorspar for metallurgical and other uses decreased by 7% (table 2). Acid-grade fluorspar was used primarily as a feedstock in the manufacture of HF.
The use of fluorspar to produce fluorochemicals via a process that bypasses HF is highly desirable but remains an unsolved problem because of the prohibitive insolubility of CaF 2. Inspired by calcium phosphate biomineralization, we herein disclose a protocol of treating acid-grade fluorspar with dipotassium hydrogen phosphate (K 2 …
