Process Development for Beneficiation of Iron Ore Slimes ...

2018-10-11 · The Iron ore processing plants have been invariably generating slimes in the range of 10 – 15% of the ROM treated. These losses are in the tune of over 15 million tons of iron values every year. The tailing ponds of most of the iron ore mines are getting accumulated with these slimes and are at the verge of getting filled.
