Comprehensive Utilization Technology of Steel Slag

  • Chapter
  • First Online:
Industrial Solid Waste Recycling in Western China

Abstract

The deposit volume of steel slag in China exceeds 400 million tons, leading to the occupation of a large area of land and serious environment pollution. However, the current utilization rate of steel slag in China is only about 21%, which is far behind that of developed countries. Recycling and reusing these solid wastes are essential, not only for conserving metals and mineral resources but also for protecting the environment. The physical and chemical characteristics of steel slag are summarized, and the pretreatment progress of steel slag in steel industries as recycled raw material was introduced. The utilization aspects (circulation in metallurgical industry, cement additive and concrete admixture, materials for wastewater or gas treatment, construction materials, and fertilizer in agriculture production, and raw materials of glass and ceramics) are introduced.
