U.S. ferrous slag production, but domestic slag sales1 in 2019 were estimated to be 17 million tons valued at about $470 million. Blast furnace slag was about 50% of the tonnage sold and accounted for 88% of the total value of slag, most of which was granulated. Steel slag produced from basic oxygen and electric arc furnaces accounted for the
Trinidad said the blast occurred in a slag pit at the steel mill along the Lake Michigan lakeshore in Porter County. Lorraine George posted on social media that she got a call that there was an explosion in the C Furnace Slag Pit at Cleveland Cliffs. Slag is a by-product of smelting (pyrometallurgical) ores and used metals, generally.
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.
