For example, the daily, weekly and monthly indices are listed because of the varied liquidity displayed by different parts of the market. Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62% Fe, 58% Fe and 65% Fe fines, and lump premium references.
(5) The lower-cost, more efficient MauMee Rotary Hearth Process that uses a Briquetted Iron Unit Feed (instead of a dried or indurated iron ore pellet) also was in the most favorable process groupings. Those processes with lower-cost raw materials (i.e. fine ore and/or nonmetallurgical coal as the reductant) had favorable combined economics.
Valero et al. proposed a general equation for estimating the energy consumption according to the ore grade: (1) E X m = A ⋅ X m − 0. 5, where E X m is the energy for the concentration and extraction of minerals at the ore grade ( x m ), and the coefficient A is determined for each mineral.
