The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as 0.1 mm or less, which are not suitable for sintering.
an increasing bias toward processing softer ore types, whereas a ratio of 1:1 or higher would indicate a bias toward processing harder ore types in selecting a "design point." This process is particularly important in selecting power levels and sizing grinding equipment for pro-cessing ore during the designated "Payback" period, as
