Producing taconite requires more processing of the ore, so the overall project – which will be designed to process 17 million tonnes of iron ore pellets and 5 million tonnes of concentrates annually – will cost an estimated $4.85 billion, for which Tata Steel would arrange the financing. A feasibility study of the taconite project is due for completion by

What is taconite used for?

The taconite pellets are brought to the steel mills to be melted down into steel. What's the difference between taconite and iron ore? Taconite is a low-grade iron ore. When the high-grade natural iron ore was plentiful, taconite was considered a waste rock and not used. But as the supply of high-grade natural ore decreased, industry began to

What is taconite and why is it used instead of just magnetite or hematite to get iron? Because of their low iron grade, taconite and magnetite require greater processing than hematite in order to form an iron concentrate product of 60-70%. The beneficiation process for taconite requires crushing, screening, grinding, magnetic separation, filtering and finally drying.
