JL Pittsburgh works did slag processing onsite. No fancy dump like USS. The JL process was multiple tracks that would dump into pits between said tracks, water jets were used to quickly cool the slag, steam shovels (later diesel) would break up and load the slag into rail cars and later trucks to be taken to crusher processor onsite.
Steel Slag - Material Description - User Guidelines for ...
The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.

Dust Control for Steel & Slag Processing | BossTek
Steel & Slag Processing Dust Control for Steel & Slag The presence of dust during steel manufacturing and recycling can create unnecessary headaches for operators as well the surrounding community. Fugitive dust particles become airborne as slag is tapped into ladles, transported and dumped into cooling areas and processed for recycling.
Steelmaking Process - an overview | ScienceDirect Topics
During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
