This blog highlights information and data I have found on
the Internet related to fluorine uses, prices, and production.
Uses. Natural occurrence of fluorine is found only when
it is bonded to other elements, primarily in the mineral fluorspar (also known as fluorite, consisting mostly of calcium fluoride). It is from fluorspar that fluorine is chemically
sourced as hydrofluoric acid (HF). The HF
is then used to react with other elements to form useful fluorine-containing
compounds. Because of the very high reactivity
of fluorine, when fluorine is reacted with other elements, very stable
compounds are formed. Fluorine, once bonded
strongly resists being un-bonded, thus providing high inertness and stability
to the compounds it is in, which is a property accounting for use of several fluorine-containing
compounds. Some of the HF produced from fluorspar
has uses as an acid, e.g., to etch glass and to process semiconducting
materials.
Prices. Two market prices relevant to fluorine use
are the price of fluorspar and the price of HF.
Internet data suggest that global 2018 fluorspar prices ranged from $400
to $500 per metric ton (mt). Several Chinese
fluorspar mine closings in 2018, due to environmental concerns, boosted world
fluorspar prices in 2018. 2018 global market
prices for HF were in the $1,000 to $2,000 per mt range. HF vendors have both the fluorspar raw material
and the HF processing costs to cover in their HF sales price.
Production. Internet data suggests that in 2018
approximately 6 million mt of fluorspar was mined. Assuming the average 2018 fluorspar price was
$450 per mt, this gives a fluorspar 2018 production value of approximately $2.7
billion (6 million mt times $450 per mt).
Internet data also suggests that the 2018 global market
value of HF produced was approximately $4.3 billion. Assuming an average HF price of $1,500 per mt
(see prices above), 2.9 million mt of HF was produced in 2018 ($4.3 billion
divided by $1,500 per mt). Industrial experience
has shown that approximately 49% of fluorspar mined is converted to HF. Using this experience, the amount of HF
produced in 2018 can be calculated a second way by multiplying 49% times 6 million
mt of fluorspar produced. This gives 2.94
million mt of HF produced in 2018, which agrees well with the amount computed
by using the 2018 HF average price and revenues.
Also from industrial experience, the amount of fluorine
produced has been about 2% of the amount of HF produced, which gives approximately
58,000 mt of fluorine produced in 2018 (2% times 2.9 million mt of HF
produced).
