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.
Basically, slag is a product of the steelmaking process. Alan Bowman of Phoenix Services, LLC, shared that slag was once scorned as a useless byproduct. "It is now accepted and often preferred as a valuable material with many and varied uses in a giant construction industry. It might be best to describe slag simply as 'manmade rock.'

Heavy slag — also known as dross — is usually associated with flamecutting or plasmacutting plate steel. Understanding how slag forms is key to learning how best to remove slag from steel. Slag is a byproduct of steel making, forming when impurities in the steel are separated from the molten metal. Typically, slag consists of limestone ...
Introducing mill scale will ensure the foam is of the amount and volume that will ensure the molten steel is completely protected by the foaming slag. Stone Production Mill scale is an ideal raw material for manufacturing highcontent stone with magnetite ore for use in highgrade food, medical, and military equipment.
Even though gas metal arc welding (GMAW) is generally considered to be a slagfree process, silicon islands present on the weld surface after welding are a normal (and largely unavoidable) byproduct of both solid and metalcored wires. Unfortunately, they can be troublesome when it comes to postweld cleanup. These islands are often small and hard to see, which can make it difficult to remove ...
