Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water ...

Slag and its Role in Blast Furnace Ironmaking – IspatGuru

The deteriorating effect of high alumina in the slag is offset by increasing its MgO content. The alumina concentration in the slag is semi-empirically set in many countries at the upper limit of around 16 % in order to avoid the accumulation of the iron slag and the deterioration of permeability in the lower part of the blast furnace.
