Sep 18, 2011· Taconite is a low-grade iron ore Originally thought to be of little value, taconite was considered overburden (waste) in the days when high grade iron ore was mined The iron content, magnetite, is only 20- 30% compared to 50 - 60 % iron content in red ore Red ore is also referred to as direct shipped ore because it can be shipped without processing
The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining
