Iron Ore Processing - eprints.nmlindia

2017-11-17  Generally, the beneficiation of high/medium grade hematite iron ores in India includes dry circuit covering crushing, screening or wet circuit consisting of crushing, scrubbing, washing and classification[3-4]. This kind of simple approach of washing and scrubbing is not sufficient enough to produce iron concentrate with desirable quality from low grade iron ores. In recent times, several development in the mineral processing in the area of gravity, magnetic separation and flotation namely column has taken place globally. However, there is need to design newer flowsheet involving advanced techniques for low grade Indian iron ores. In the present investigation, an attempt made to produce sinter grade fines and also the pellet-feed material from a low grade iron ore sourced from eastern region of India by using various beneficiation techniques.
