Recycling and environmental issues of metallurgical

Steel slag is a secondary resource of raw material in metallurgical plant. It can be directly taken back to sintering, ironmaking and steelmaking, and used as flux, from which the useful elements can be recovered7. It is advantage that the premelted flux is more easily remelted than the raw flux. On the other hand, steel slag can be used as
