Application/Uses

4.

Salient Technical Features including Competing Features

The process is based on upgradation of dumped low-grade iron ore fines involving scrubbing-washing-classification of the dumped fine ore followed by gravity and magnetic separation of classified materials. The process ensures optimum recovery of iron values through closed loop operation and processing of intermediate products.

5.

Level/Scale of Development

0.5 tph. Further scale-up is possible.

6.

Environmental Considerations

The process is environmental friendly. However tailing disposal system needs to be in place
