N2 - The effectiveness of using different beneficiation techniques of low-grade iron ore deposits of Assen iron ore mine in Thabazimbi, South Africa has been investigated. The sample received was confirmed to be low grade haematitic iron ore containing (39.18% Fe and 40.29% Si) both lumps and fines. The most abundant gangue present was silica. The different beneficiation methods such as shaking table, drum magnetic separation and reverse flotation were compared on the basis of which one yields a better grade that can be utilized in pellet making, and the results are discussed. A shaking table could upgrade to a suitable grade required in pellet making of 61%, however it yielded a very low recovery of 37%.The highest recovery was obtained using reverse flotation at 76% and it also yielded the highest grade at 63%. A conclusion was hence made that reverse flotation is the utmost suitable upgrading technique of iron ore.
