### Beneficiation of iron ore slimes Semantic Scholar

1 天前 Current trend in mechanisation of hematitic iron ore mines is to meet the requirement of steel industry for production of lump ore of specified size and fines for sinter manufacture. The general processing method being adopted is washing, wet screening and classification of wet screened fines. Usually classifier/cyclone overflow slimes are rejected. The table-1 gives an idea of the quantity of ...

Beneficiation is the process of separating iron ore from the gangue particles like alumina, silica. Increasing the iron ore demand, with the faster depletion of high grade iron ore, it is the time to use low grade iron ore slime as a feed stock rather leaves as a waste. Mainly coarser fraction is rich in iron content and finer fraction contained large amount of gangue.
