  1. Complete Smelting Solutions Tenova Pyromet Speaker: Bruce Nourse Position: General Manager – Technology Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  2. Tenova Pyromet: What do we do? Mining Concentration Smelting Steel Industry Base Metals Refining Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  3. Tenova - furnaces since 1935

  4. Tenova – some development history 1935 First Tagliaferri furnace KT Lance 2000 Consteel 2001 Maxicool copper coolers 2003 Titania DC furnace 2008 Multiple preheater 2011 Dry gas scrubbing 2012 Gas suspension preheater 2013 Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  5. Tenova Pyromet Typical processes: • Ferrochrome - more than 50, up to 66MVA, 84MVA design in progress • Ferromanganese and Silicon Manganese – more than 30, up to 45MVA • Copper/Nickel/Platinum slag refining – 36MVA • Platinum – 12.5MVA Circular PGM smelter • Ferronickel – 66MVA design • Silicon alloys – 3 furnaces in last 3 years, 30MW design complete • Ilmenite – 30MW DC • Iron – 48MVA design in progress Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  6. Tenova Pyromet Main drivers influencing development: • Ore • Mineralogy is changing (easily mined ores exhausted) • Reductants • Availability vs cost • Power • Limitations imposed • Cost • Environmental • Effluent • Water usage Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  7. Tenova Pyromet Recent technology developments by Tenova Pyromet: Dry Gas Scrubber Multiple Pre-Heater Gas suspension Pre-Heater Reduce Power Consumption High efficiency gas cleaning Reduce Power Consumption Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  8. Tenova Pyromet Dry Scrubber Advantages: • Allows the use of lower quality reductants • Uses less water than venturi scrubbing • Manage tar issues in the gas • Energy recovery through combustion of waste gas Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  9. Tenova Pyromet Multiple Pre-Heater • Reduces power consumption by pre-heating feed materials • Can be retrofitted to some existing furnaces • Reduces furnace building height and subsequent overall plant footprint • Effectively utilise energy contained in furnace off-gas • Best suited to furnaces with agglomerated feed Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  10. Tenova Pyromet Gas suspension Pre-Heater • Reduces furnace power consumption • Higher feed temperature achievable • Proven technology, new application • Suited to furnaces using fine feed materials (typically DC furnaces) Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013

  11. Tenova Pyromet Tenova Pyromet focus is offering ‘complete smelting solutions’ by targeting the following: • Development of focused technologies in-house • Strategic partnerships - Develop beneficiation and refining technologies • Total package - Being able, together with other Group companies, to offer clients a ‘1 stop shop’ for project development and execution • Not limited by technology offering, so can objectively offer technology to best meet client needs Pushing the Boundaries of Technology 4 Innovative Client Solutions Tenova Mining & Minerals southern Africa Client Symposium,Johannesburg, 03 October 2013
