Iron ore pricing explained | Metal Bulletin.com

Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke ...

Ore Grade Reconciliation Techniques – A Review

The essence of ore grade reconciliation is to identify, analyse and manage variance between planned and actual results in a way that highlights opportunities. A consistent record of poor reconciliation is an indication that this variance has not been adequately managed. This would inevitably result in significant economic impact on mining companies.
