Slag-What is it Good for? | U.S. Geological Survey
Slag. Depending on where you’re from, it may be an insult, a term meaning trash, or, in our case, the waste left over from metal smelting or refining. Outside of the construction industry, it might seem that uses for slag are considered limited.

Crystallization Behavior of Copper Smelter Slag During Molten
Copper slag is composed of iron silicate obtained by smelting copper concentrate and silica flux. One of the most important criteria for the utilization of this secondary resource is the recovery of iron from the slag matrix to decrease the volume of dumped slag. The molten oxidation process with crushing magnetic separation appears to be a more sustainable approach and is based on directly

Smelting
D. Zhu, in Iron Ore, 2015. 16.3.2.1 Background. Smelting is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke

Iron smelting
The slag floated on top of the iron and after a few hours, the molten iron flowed out through a tap hole at the bottom of the furnace. The slag flowed out through a tap hole higher up. The iron cooled and hardened into ingots – pig iron. Some of the slag was cast in molds – clinker blocks – which were used as construction material.
