Abstract: Because of the stacking covers and environment pollution problems increasingly prominent, the research of refining slag recycling is most great significance to enterprise's energy conservation and emissions reduction. The research status of recycling LF spent slag and the major problems were analyzed. It is considered that the focus of future research to the LF spent slag is the desulfurization. LF refining slag contains a lot of useful components, as long as the slag removes the harmful elements, LF refining slag can be recycled. Scholars have conducted extensive research on desulfurization in order to promote the LF refining slag recycling, and have made many achievements. It has great significance for achieving energy conservation.

Key words: LF refining slag, recycling, desulfurization, sulfur incorporation mineral
