1 Towards the AEI Guidebook Maintenance Plan: additions to the Nickel Production Chapter Outline of 2009 contribution in-kind of Belarus to EMEP 10th Joint EIONET and the Task Force on Emission Inventories and Projections Meeting 11-12 May 2009, Vienna, Austria Sergey Kakareka, Tamara Kukharchyk Institute for Nature Management National Academy of Sciences Minsk, Belarus

2 Summary Included into presentation: 1. Rationale 2. Proposed additions to the 2.C.5.c Nickel production chapter - Overview of nickel products and industry - Principal technologies and schemes - Emissions and abatement - Tier 1 and Tier 2 EF tables

3 Current status of the 2.C.5.c Nickel production chapter - too schematic description of technological processes; - Tier1 EF are relevant only for hydrometallurgical technology. If applied these factors for total Europe nickel production annual SOx emission in Europe will be about 8-9 thous. tonnes while real emissions in EMEP domain from nickel production are about 20 times higher, in extended EMEP domain – 100-120 times higher; - no Tier1 EF for pyrometallurgic technology; - no TIER 2 EF which are necessary for accurate and complete emission inventory from nickel production.

4 Proposed additions into: Overview Nickel products At the market nickel is presented in different brands. Metallic nickel is divided into two main classes: refined nickel (nickel cathodes (greatest), briquettes, granules, rondelles, powder/flakers etc.) and charge nickel (ferronickel, nickel oxide sinter, secondary nickel). Less part of nickel is produced also as nickel chemicals.

5 World nickel production (USGS data) World nickel production in 2005 according to USGS amounted 1,3 mln. tons World nickel production by types of products Main types of nickel products: Metal Metal Ferronickel Ferronickel Chemicals Chemicals Oxide sinter & oxides Oxide sinter & oxides

6 World primary nickel production by country %, (2005) Main primary nickel production countries Russian Federation – 287 thous. t ; Japan – 167 thous. t; Canada – 140 thous. t; Australia – 122 thous.t

7 Nickel primary production in Europe, % (2005) Main primary nickel production countries in Europe Russian Federation – 287 thous. t Norway – 85 thous. t Finland – 44 thous. t United Kingdom – 37 thous. t Nickel primary production in Europe in 2005 amounted 509 thous. tons

8 Production of nickel by types of process in Europe Ratio of nickel production by type in Europe Nickel from ore (full cycle of nickel production): - Russian Federation - Greece (ferronickel) - Macedonia (ferronickel) Nickel from matte: - Norway - Finland - France - United Kingdom Nickel from ore (full cycle of nickel production): - Russian Federation - Greece (ferronickel) - Macedonia (ferronickel) Nickel from matte: - Norway - Finland - France - United Kingdom

10 Technologies and main processes in nickel production Pyrometallurgical technology: Pyrometallurgical technology: from sulfidic ores: ore concentration–roasting-smelting- converting-smelting-refining;from sulfidic ores: ore concentration–roasting-smelting- converting-smelting-refining; from silicate ore: smelting-converting-smelting- refining); specificity: coke or coal as fuel, pyrites as additives;from silicate ore: smelting-converting-smelting- refining); specificity: coke or coal as fuel, pyrites as additives; from laterite ore: drying calcining-smelting-converting to matte or ferronickel.from laterite ore: drying calcining-smelting-converting to matte or ferronickel. Hydrometallurgical technology: Hydrometallurgical technology: from laterite ores: ammoniacal leaching-hydrogen reduction to oxide sinter;from laterite ores: ammoniacal leaching-hydrogen reduction to oxide sinter; from matte: chloride or sulfuric acid leaching or carbonyl process - refining.from matte: chloride or sulfuric acid leaching or carbonyl process - refining.

14 Particulate emission: battery cyclones, ESP, wet scrubbers at agglomeration and smelting stages. Level of abatement: 92-99% (EECCA). SOx – waste gases washing with further sulfur or sulfuric acid production. Level of desulfurization - up to 75%. SOx emission depends on sulfur content in ore, technology, SOx content in waste gases, possibilities of sulfur from gases utilization. into: Emissions and control

21 Application of results Spatial resolution of SOx emission can be improved. For instance, it is seen that Cola Peninsula SOx emissions in Webdab (32.4 thous. tones for 2005), used for EMEP modeling are underestimated taking into account nickel-copper production facilities in this region. SOx emission by 50x50 EMEP grid in 2006, tonnes (WebDab)

22 - SOx and PM emission factors seems rather low uncertainty; - HM emission factors are highly uncertain (except Ni and Cu); As, Pb, Cd emissions are expected when pyrite is used in technological process. Uncertainties

23 - proposed addition aimed at improvement of applicability of the Guidebook chapter for real life emission inventory work; - it is difficult to divide emission by product when different products (metals: nickel, copper, cobalt etc. ) are produced at the same plant: special comments are necessary in Data Quality section which will allow to exclude double counting or missing sources; - sources of statistical data need to be shown; - bibliography to be improved. Concluding remarks

24 Plans for 2010 in-kind: - further improvements to the GB in view of POPs, HM and overall in view of EECCA countries technological specificity.
