Steel slag in China: Treatment, recycling, and management
Typically, slag material that is larger than 25.4 mm in diameter is highly metallic and recycled as scrap. The finer the particle size, however, the higher the recycling rate of magnetic content and the greater the recycling cost. Fine steel slag below 12.5 mm is the most difficult to utilize, partly because of its high impurity concentration.
