Calcium leaching from waste steelmaking slag: …

Accelerated carbonation of alkaline wastes such as steelmaking slag offers the potential to coine waste valorisation with climate change mitigation by utilising carbon dioxide (CO 2).One method of achieving this is through an indirect carbonation process to produce a marketable precipitated calcium carbonate (PCC), using ammonium salts to selectively extract calcium from steelmaking slag.
