Transcript of "World leading Finnish technology: history and future outlook- Kari Heiskanen, Aalto University"

  1. 1. “World leading Finnish technology: history and future outlook” Kari Heiskanen D.Sc., professor Aalto University
  2. 2. Content • Some theses to start with • A few worlds of history • Discussion of processing paradigm • Discussion of operations paradigm
  3. 3. Some theses to start with • Paradigm levels –Operations, production • Paradigm development – Effects on technology offerings • Paradigm orchestration – Technology breakthroughs
  4. 4. Operations paradigm • Compartmentalisation – Mining as a technical exercise • Emphasis on production development – Mining as an economical exercise • Mining as an techno-economical exercise – Life time costs – Services – Complete technical solutions
  5. 5. A few words of history • Roots of the existing technology level are – During compartmentalized operations paradigm – Engineering and maintenance arms of operating companies • Individual inventors within these organisations • Focused on engineering and local needs.
  6. 6. A few words of history • The history has taken us to consider more solving the processing issues – Better, bigger and more efficient machines
  7. 7. Weighted average percentage head grades of copper mines, 1970 onwards. Crowson P., Some observations on copper yields and ore grades, Resources Policy Volume 37, Issue 1 2012 59 – 72

  19. 19. Changes • Changing conceptions of Nature • Social Media • Position of raw materials in the value chains – Perceptions • Society averse to risks
  20. 20. Big issues to be tackled by changing the operations paradigm • Energy, • Waste and other emissions, • Water, – use and waste water release • Workforce, • Local societal fabric.
  21. 21. Operations paradigm • Compartmentalisation • Mining as an techno-economical exercise • Systemic exercise –Environmental and social issues affect strongly and form major constraints when optimising the operations
  22. 22. Systemic paradigm • Energy – New ideas on comminution • Will the SAG become obsolete in 10 years? • Tailings – Tailings treatment • Water – Real closed water circulation (indoors) • No wet tailing ponds
  23. 23. Conclusions Paradigm shift will happen Do we want to lead or follow?
