1 Emerging trends in the industry deriving fluorine from phosphate Alain Dreveton (Eng. INSA Toulouse, DEA) AD Process Strategies SARL Rue Chaponnière 9 CH-1201 Geneva / Switzerland a.dreveton@adpro-stg.com

2 Emerging trends in the industry deriving fluorine from phosphate General trends in mining sectors of fluorspar and phosphate Re-industrialization of the fluorine industry outside China? FSA as a potential source of HF Cost comparison between FSA and fluorspar as source of HF

3 Markets overview: drivers & News HF, Closure Amherstburg, Overcapacity China, New cap. Aluminium fluoride, Overcapacity China, New cap. STF affected by crisis of Solar Industry HFO-1234yf replaces HFC-134a

4 Markets overview: drivers & News HFC-125, etc PVDF LiPF6 & Li-based Electrolytes LiPF6, US plant cancelled FEC NF3, F2, UHP HF Battery, Solar, Polymers CDM HFC-23 another scandal to come Safety issues Environmental issues

5 F abundance Fluorine as abundant as P, C, S, Mn, more abundant than Cl, Cu, Not qualified of critical Exploration?

6 Three raw materials Fluoride from Fluorspar Fluoride from DUF6 Fluoride from Phosphate

7 Fluorspar Fluoride from Fluorspar CASE OF EUROPE Production in Spain, Germany, UK, Bulgaria Exploration in Sweden, France, Germany, etc (& Norway).. AD Process Strategies promotes up to 10 fluorspar projects - Largest is up to 20 millions tonnes - At early stage of development to the level of feasibility study - Know-how is available

8 DUF6 Babcock Wilcox plants operating in Piketon (OH) & Paducah (KY) INTL Isotopes (another project under planning still to come using Starmet patents) Rosatom commissions a small plant for DHF and AHF using Areva know-how

9 DUF6

10 Fluoride from phosphate

11 Fluoride from phosphate AGF G. Wengfu MTPA AHF ( future ?) Dazhou MTPA AHF Zijin MTPA AHF G. Kailin MTPA AHF Hubei Xingfa 3 x MTPA AHF At least 2 more cooperations in Yunnan, China STF PCS Phosphate/ SunEdison (MEMC) MTPA STF (US) AlF3 & Fluoride wet process not discussed

12 Fluoride from phosphate The largest phosphate producers have studied HF from FSA Morocco, Jordan, RSA, KSA, etc and none have implemented the technology? AD Process Strategies is in touch with this industry for potential projects

13 Fluoride from phosphate General trends in mining sectors of fluorspar and phosphate Phosphate industry is expanding in Morocco, Saudi Arabia, Jordan, China, etc Mega project are financed by International Institutions, Consortium of Banks Fluorspar are smaller projects promoted by Juniors / start-up companies Established companies are strengthening their positions Technology not yet assimilated

14 Process HF and AlF3 from fluosilicic acid 1G

15 Process HF and AlF3 from fluosilicic acid 2G

16 Process HF and AlF3 from fluosilicic acid 3G

17 Process HF and AlF3 from fluosilicic acid 4G Phosphate Production (fluorochemical production) Safe & cheap Transportation Generation of AHF - Standalone plant at Phosphate site - Removal of water - Standalone plant at End-user site - On-demand production AHF - Safe, no byproduct, no pollution,..

18 Economics of FSA versus CaF2 - assumptions Capacity MTPA AHF, typical case Capital cost estimated for Emerging Countries Plant & Utilities as required Prices eg raw materials, chemicals per end 2012 Logistics for shipping overseas Interest per annum All assumptions for Emerging Countries Economics (as a function of price of AGF 97% CaF2 Min) Economics (as a function of price of FSA 100% H2SiF6)

19 Economics of HF from fluorspar - features High mining costs for fluorspar exploration, mining, Beneficiation,.. Fluorspar is expensive Sulphuric acid & oleum are consumed End-use for anhydrite gypsum is required Fluorspar technology is mature, cost effective Plant is Standalone Site preferably at mine, at harbor for AlF3 Site preferably at end-user site for AHF

20 Economics of HF from fluosilicic acid - features Savings of significant high mining costs Recovery of fluosilicic acid >~ 21% Technology relatively new Raw material are free except ATF for AlF3 manufacture Fluosilicic acid can be cheap Sulphuric acid is not consumed No critical waste Silica is a potential product Chillers for cooling water are included Plant is Not Standalone as large volume of diluted sulphuric acid has to be fed to the Phosphoric acid plant Arsenic removal is required for AHF manufacture only AHF containment tank and fleet of ISO tank containers required

21 Information on fluorspar (AGF) price China USD/MT October 2013

22 Economics of hydrofluoric acid Competitive advantage only against (2) and (3) for Phosphoric Acid Producers (FSA is free) (FSA) (1) FSA cheap (1) AGF mine owner (2) (2) AGF actual price in China (OK) (3) AGF traded on World Market (OK) (2) (AGF) (3)

23 Economics of hydrofluoric acid (2) Not competitive against fluorspar mine owners FSA medium price (FSA purchased) (1) No advantage versus AGF mine owner (In China or outside) (2) In competition with AGF in China (FSA) (1) (2) (3) Competitive versus AGF traded on World Market (AGF) (3)

24 Economics of hydrofluoric acid (3) Not competitive FSA too high price (FSA purchased) (1) (1) No advantage versus AGF mine owner (I/O China) (2) In competition with AGF in China (3) Competitive versus AGF traded on World Market (2) (FSA) (AGF) (3)

25 Economics of FSA versus CaF2 - safety Fatal accident in South Korea Killed 5 Derailment in USA

26 Economics of hydrofluoric acid - safety AHF containment tank and fleet of ISO tank containers - Safety first -

27 Economics of HF - conclusions Better is production of AlF3 w or w/o HF FSA Capacity is an advantage AlF3 producers (AGF) non integrated are at risk Recommend to study in detail projects Locate downstream productions at fertilizer sites eg HFCs Plan environmental units from early conceptual stage Alliances / JV to favor for AHF
