Previous tests in the 1970s found that the fluorspar at Storuman was not suitable for plants producing hydrofluoric acid. Tertiary said in a statement: "The latest test, carried out on more coarsely ground material has produced saleable fluorspar concentrate within the grain size limits required by acid-grade .
One of the world's leading experts on industrial chemicals explains the convoluted market for fluorspar, a component of many household products. In this interview with The Critical Metals Report, IHS Chemical's Ray Will explains how a rebound of the global supply of fluorspar is tied to the fluctuating trade agenda of the mineral's largest consumer, China.
Hastie Mining, based in Illinois, US, produces 10,000 tonnes per year of fluorspar, most of which is metal-grade spar, 90% CaF2 purity or lower and used for production of metals. Meanwhile, the US imports around 82.5% of its fluorspar for manufacturing hydrofluoric acid, which requires 97% CaF2 fluorspar.
Acid grade fluorspar which is in great demand by the chemical and aluminum industries, must contain at least 97.5% CaF 2 with not more than 1.5% SiO 2 and 0.5% Fe 2 O 3. Often the Silica is limited to 1.2% with penalties starting at 1.0% SiO 2.
