Large amounts of steel slag (SS) and CO 2 are produced globally each year during steel production. An SS-based carbon capture and utilization (SS-CCU) process for CO 2 mineralization is suitable specifically for steel-making industries for simultaneous mitigation of CO 2 emissions and valorization of wastes. However, the SS-CCU process …Web

Calcium oxide (KAL-see-um OK-side) is an odorless crystalline or powdery solid that, in a pure form, is white to off-gray. It often appears with a yellowish or brownish tint to the presence of impurities, especially iron. Calcium oxide reacts with water to form calcium hydroxide (Ca (OH) 2) with the evolution of significant amounts of heat.Web
