  • EU to impose carbon border adjustment mechanism on steel, Al imports, other products

    Friday, 11 June 2021

    The European Commission (EC) plans to set a carbon border adjustment mechanism (CBAM) for imports of some goods, including steel and aluminium, to prevent the risk of carbon leakage, according to a draft of the EC’s proposal seen by Fastmarkets on June 10.

  • Container shipping bottleneck emerges amid southern China's Covid-19 fight

    Wednesday, 09 June 2021

    A rise in Covid-19 cases in China’s Guangdong province in recent weeks has led to tighter controls and rigorous testing at the huge Yantian International Container Terminal (YICT), causing extended delays in southern China.

  • Shipping's container chaos to continue, DP World exec says

    Wednesday, 02 June 2021

    The chaos being experienced in the global container shipping industry is expected to continue for some time with a shortage of an estimated four million boxes creating havoc with congestion, routes and freight rates, according to an executive at logistics conglomerate DP World.

  • Rotterdam almost clear of Suez blockage backlog, Port Authority says

    Wednesday, 12 May 2021

    The so-called “Suez Armada” of vessels that were delayed by the unintentional blockage of the Suez Canal has now been processed by the Port of Rotterdam, but the port was still “extremely” busy and there were challenges ahead for the shipping sector, speakers said during the Supply Chain Talks digital event on Wednesday May 5.

Market Brief

Fluorspar is the commercial name for fluorite, a form of calcium fluoride (CaF2). Pure fluorite contains 51.3% calcium and 48.7% fluorine.

Fluorite is the primary source of fluorine, however relatively minor sources of fluorine include cryolite (Na3AlF6), sellaite (MgF2), topaz (Al2SiO4[F,OH]2), villiaumite (NaF), bastnasite ([Ce,La][CO3]F), and fluorapatite (Ca 5[PO4,CO3]3F).

Naturally occurring cryolite, used in the aluminium smelting process, has largely been replaced by synthetic cryolite.

Fluorspar may be found in a range of geological environments, such as hydrothermal and sedimentary, associated with barytes, calcium carbonate, galena, pyrite, quartz and sphalerite.

Fluorspar grades are categorised on the basis of CaF2 content. Major grades produced include:

Other grades include:

Another source of fluorine is fluosilicic acid (FSA), made as a by-product from the processing of phosphate rock into phosphoric acid for the fertiliser industry. FSA for its fluorine content has primarily been used as a water additive, particularly in the USA.

Supply

The world's identified resource of fluorspar is approximately 500m tonnes contained. However, if reserves of fluorine present in phosphate rock are also considered, then this adds a further 1.29bn tonnes of fluorspar (or 630m. tonnes of fluorine).

South Africa is the single largest holder of these reserves (18%) with 41m tonnes of fluorite reserves, followed by Mexico (14%) with 32m tonnes, China (9%) reporting 21m tonnes, and Mongolia (5%) having 12m tonnes.















Nearly 49% of the reserves are not commercially mined or produced.




World fluorspar production capacity is about 6.3m tpa (2012), and is dominated by China (50%) and Mexico (18%), followed by smaller production in Mongolia (7%) and South Africa (3%). Countries including Russia, Namibia and Spain account for 2% each, while Kenya and Morocco contribute 1% individually.














World's major fluorspar producers include:

Mexichem – Mexico

Steyuan Mineral Resources Group – China

Mongolrostsvetmet LLC – Mongolia/Russia (JV)

Minersa – Spain

Kenya Fluorspar – Kenya

Vergenoeg Mining Company – South Africa

Masan Resources – Vietnam

British Fluorspar – United Kingdom

Markets







There are two principal grades of fluorspar, which are defined based on the CaF2 content of the material. Metallurgical (and ceramic) grade fluorspar contains ≤97% CaF2, while acid grade fluorspar contains ≥97% CaF2.

Metspar is primarily sold as a flux into markets for iron and steel casting and steelmaking.

Acidspar is the raw material for hydrofluoric acid (HF) and thus for all fluorochemicals, in addition to being an important feedstock for aluminium fluoride (captive) and other markets (such as welding rods).

Around 60% of fluorspar produced in 2008 was classed as acid grade, with the balance classed as metallurgical grade.
