Comprehensive utilization of steel slag: A review
Introduction. Steel slag is the main solid waste generated in the steel-making process, accounting for 15 to 20% of crude steel output [1]. China's crude steel output in 2021 was 1.035 billion tons [2], more than half of the global crude steel output (1.9505 billion tons) [3], and the steel slag output exceeded 120 million tons.
