Historien
1908
Start elproduksjon I Tyssedal
1914
DNN Etablert, start Aluminium 1916
1976
Staten kjøper DNN
1979
Aluminium rives, nybygging starter.
1983-86 Bygging og oppstart av
K/S lmenittsmelteverket A/S
1988
Staten selger til Tinfos, navneskifte:
Tinfos Titan & Iron (TTI)
1995-2001 BHP kommer inn som minoritetseier.
2008
Tinfos selger seg ut til Eramet
2010
Navneskifte
Tinfos Titan & Iron  Eramet Titanium & Iron
2011
Joint venture Eramet-MDL
2012
Navneskifte
Eramet Titanium & Iron  TiZir Titanium & Iron

TTI H2 development project:
• Turnover : +/- 1 bill Nok/year
• 180 employees
• R&D expenditures 2011-2014:
+100mill Nok.
• Investment 2015 : 500 mill Nok
• Investments 2016-2020: 2,3 bill Nok
•
New mine in Senegal started 2014
• Ilmenite well suited for H2 reduction

Some variables to deal with :
• Market prices for our products (Sulphate slag, Chloride slag, Ilmenite, rutile & Zircon …)
• Energy prices and availability going from 330 to 1700GWH
• Emission (CO2) – and transition costs
• Logistic costs between Senegal and Norway and our customers
• Positioning of TTI on the TiO2 “ cost curves”. Nearly 100% of our product are exported
worldwide.
• Risks, political and market
8
Looking forward
• The current program is the first step of a major evolution
• Norway enjoys and will continue to enjoy favourable electricity supply
conditions
• At TTI our next steps are:

Strongly reducing our environmental footprint and our:

CO2 emission /t slag

Specific energy consumption

Increasing our capacity of production

Being prepared to become the
top GREEN smelter on the market

Major development since the establishment of TiZir
Our long term goal is to increase our presence on the
market and become the GREENEST TiO2 feedstock
producer.

Via the start up of Grande Côte and the
refurbishment of TTI Furnace
Within very versatile and cyclical markets, our size (circa 8% of the world MS) and our process allow us the
flexibility and the ability to adapt to changing conditions.
