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
phase the initial phase of mining, from discovery until the was for direct shipping ore these ores were pockets of high grade iron concentrations that formed within banded iron formations by leaching of silica by surface water or deeply circulating ground water. phase beginning in the late a but by the most of the easily accessible ore with high concentrations of iron was gone, and mining companies had to dig much deeper and develop new techniques to extract and concentrate iron from lower-grade ore. today, mine operators in michigans upper peninsula are generally after taconite, a low-grade ore that was once considered
