An Overview of Utilization of Steel Slag

The current utilization rate of steel slag is only 22% in china, far behind the developed countries. At present, the amount of slag deposited in storage yard adds up to 30Mt, leading to the occupation of farm land and serious pollution to the environment. Improving the slag utilization is an important way to resolve these problems.

Slag-What is it Good for? | U.S. Geological Survey

Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers' current waste footprint.
