How is Iron Refined from Ore? (with pictures)

To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.Carbon fills this role nicely, and is readily available in the form of everyday charcoal, or coke, a form of carbon made from coal.

Iron ore (fines)

Iron ore is the raw material used to make Pig Iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

Mine improves operations through OEE and waterfall analysis

The world-class OEE for manufacturing is usually about 80%, with variations in availability between 85 to 90%, and performance at about 90% or higher. Quality in manufac-turing is usually represented by the average outgoing qual-ity level of the process. The ore quality for hoisting can be constantly treated at , however, because hoisting is a physical operation, and no transformation occurs. Thus, world-class OEE = availability x performance x quality = 0.9 x 0.9 x 1.0 = 0.81 ≈ 80% Now, let''s perform an example exercise of hoist OEE …
