goethite-rich mineral tends to generate fine fraction known as fine ore having size below 8 –10 mm. Dry processing of iron ore is popular for treating hard massive hematitic ores; however, fines generated during processing of goethite-rich mineral cause significant quantity loss of iron values in rejects and make the process inefficient.
The process is not suitable for separation of fines and moreover, uses a huge amount of water. In iron ore beneficiation plants, the spiral concentration technique is being used to obtain a fine concentrate. In spiral separators, the separation of heavy and light minerals takes place in streaming currents.
This has significant implications for ironmaking, as goethite-rich ores are typically softer and more friable in nature, giving rise to the generation of a large proportion of Fe-rich fines during ...
