  Reduction of CO2 Emissions from Steel Plants by Using ...

  Apr 23, 2010· In a country like Finland, where no suitable geological formations for CO 2 storage seem to exist, steelmaking slag carbonation offers an important CO 2 emissions reduction option for steel plants. If calcium could be extracted selectively from the slags prior to carbonation, a pure, and possibly marketable, calcium carbonate may be produced.
