    Thursday, 27 April 2017

    See article below, from the May issue of Industrial Minerals, for market updates on price movements in various industrial minerals. Minerals featured this month include: lithium, graphite, chromite, alumina, fluorspar, magnesia, antimony trioxide, fluorspar, rare earths, silicon carbide

  • Price briefing 31 March – 6 April

    Friday, 07 April 2017

    Chromite buying activities may increase in Q2; fluorspar prices outside China flat but demand expected to improve; spherical graphite stagnant; white fused alumina prices fall

  • China supply disruption fails to lift fluorspar prices elsewhere

    Friday, 07 April 2017

    Despite the recent uptrend of China-origin fluorspar, prices elsewhere in the world have remained largely stable as consumers remain well-covered by long-term contracts. Amid improving demand and the ongoing anti-pollution related supply cut in China, some are optimistic of a recovery following six years of depressed demand and falling prices.

    Friday, 24 March 2017

    Lithium prices unchanged; brown fused alumina spreads widen; fluorspar continues to climb; antimony trioxide stable; chromite stand-off continues

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Naturally occurring cryolite, used in the aluminium smelting process, has largely been replaced by synthetic cryolite.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