The need for new manganese alloy capacity and where it will emerge in the future
Kevin FowkesManaging Consultant
Metal Bulletin 28th International Ferroalloys Conference
Berlin, 12th November 2012
• Manganese is the world’s fourth most heavily consumed metal
• Global mine output of 15 million tonnes in 2011 – over 90% goes into steel
• All steels contain manganese
• Manganese is used to remove sulphur from liquid steel(sulphur causes steel to crack)
What is manganese?
(sulphur causes steel to crack)
• There is no viable substitute for manganese as a de-sulphuriser
• Manganese is also used to improve the strength of certain steels(structural steels, high strength flat steels)
• Non-steel consumption of manganese includes de-polarisation of dry-cell batteries, and as an additive in certain aluminium and copper alloys

More positively, there are reasons to believe that the average Mncontent of steel will continue to rise
Structural steels require strength,
so tend to have a high manganese
content
Developing countries focus more on
structural steel consumption – for
infrastructure and buildings

ConclusionAnalysis of Mn smelting potential by region
• South Africa
• Middle East
• USA
• Huge nominal capacity of ~15 million tpy of Mn alloys
• New capacity still being built despite well-publicised closures
• Export taxes render export markets unprofitable, but future of export taxation uncertain in face of WTO opposition and economic slowdown
• Smuggling via Vietnam already a major factor in Mn metal & FeSi markets
Future Mn alloy smelting potentialChina
• Smuggling via Vietnam already a major factor in Mn metal & FeSi markets
• China has not become significant net importer of Mn alloys; where this has become the case (eg FeCr), it is diminishing
• Uncertainty over slowdown of Chinese steel growth – could this eventually lead to a return of Chinese exports?
• Environmental factors will become more important – in Mn metal especially
• High market power prices, but captive power plants common
• Labour costs cheaper than China
• Expansion of ferroalloy production driven by anticipated growth of steel output which hasn’t happened yet
• Consequently, Mn alloy exports have risen substantially
Future Mn alloy smelting potentialIndia
• Consequently, Mn alloy exports have risen substantially
• Increasing reliance on imported ore – from 10% to 50% of consumption over past 5 years – especially for FeMn production
• Arguably exports have “maxed out”, and may reduce as rising local steel production absorbs more Mn alloys
• However, Indian Mn consumption per tonne of steel is highest in the world, and will gradually fall more in line with rest of world
• Potentially low power prices & low labour costs
• But highly dependent on future market growth and what happens to China
• Restrictions on ore exports may force more local smelting (eg Indonesia)
• Proposed projects:
Future Mn alloy smelting potentialRest of Asia
− OM Holdings, Sarawak, Malaysia265,000 tpy Mn alloys, 310,000 tpy FeSiCommissioning 2014-2015
− Asia Minerals Limited, Sarawak, Malaysia350,000 tpy Mn alloys & FeSiCommissioning 2013-2014
− Indonesia
• Numerous ongoing expansions, focused on HC FeMn:
− New furnace at BHP Billiton Meyerton
− Gradual conversion of Assmang Machadodorp now 75% complete
− Kalagadi smelter
Future Mn alloy smelting potentialSouth Africa
− Total effect of above +700,000 tpy extra HC FeMn output
• Power situation in South Africa increasingly favours switching to HC FeMnfrom SiMn and FeCr – strong possibility of further conversions to come
• Plentiful local availability of good quality ore – labour & reductant costs very competitive
• Low power prices can be negotiated (<$40/MWh)
• Plentiful local capital availability:
− Sovereign wealth funds full of oil & gas revenues
− Ambition to diversify into local non-oil & gas projects
Future Mn alloy smelting potentialMiddle East
− Sharia compliance and small project size can be problematic
• Rapidly growing domestic market
• Political risk
• Poor track record of previous Middle Eastern ferroalloy projects
• Impact of shale gas revolution on energy prices is a game-changer
• Large, resilient domestic market, over-reliant on imports
• Stringent environmental regulation, but much worse for old sites
• Competitive labour costs away from highly unionised rust belt
Future Mn alloy smelting potentialUSA
• Competitive labour costs away from highly unionised rust belt
• Potential expansion of existing capacity & switching from FeSi
• Potential Mn metal projects based on very low-grade domestic ores
• Resource self-sufficiency becoming major issue
