Oct 04, 2017 As above-water-table, high-grade ore deposits decrease in abundance, and producers increasingly start to extract ore from below the water table, the wet and sticky ore problem is having an increasing impact on the iron ore value chain. Wet and sticky ore can lead to a disrupted flow during processing and transport.
Major problem faced with the Indian iron ore is that though they are very rich in iron content they also have a high content of gangue material like silica and aluminium which obstruct the iron and steel production as the performance of the blast furnace lowers. Iron ore sample found is a part of banded iron ore formation.
