Slag recycling - recovery

With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron. In the case of inferior grade ores below 60 %, the amount of slag is typically 0.35 to 0.50 slag/t of pig iron [1].

Iron Recycling - Cohen

Iron ore – most commonly, hematite and magnetite – goes through a process known as sintering to create pieces that are 10-25mm in size. These pieces enter the furnace along with coal (known as “coke” in this context), which provides the heat, and limestone, which makes any impurities in the ore rise to the top to form a layer called slag .
