Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes ...

Therefore, the explicit profit of the proposed system in slag lifetime was 32.02 $/t slag. However, as we all know, the main by-product of BF slag was unavoidable in the ironmaking process, so the implicit profit of the proposed system should exclude the compulsory cost. Finally, the implicit profit of the proposed system reached 136.32 $/t slag.
