Iron recovery from dry tailing dumps of an iron processing plant using an efficient circuit

This work aims at investigating the production feasibility of a high yield product from a landfill suitable for feeding to an iron concentration plant. For this purpose, the samples were taken from tailing dumps of 3 Chahoun mine contained less than 10% iron content. After primary sample preparations, the representative samples were divided into two parts i.e. coarser and finer than 4 mm. it was concentrated by a medium intensity magnetic separator (MIMS) with a velocity of 1.5 m/s at rougher stage. The tailing and product were crushed by a jaw crusher down to 10, 6, 2 mm and followed by a low intensity magnetic separator (LIMS) with speeds of 1.5, 3, 4 m/s in the cleaner and scavenger stages. The results show that iron recovery is most likely to occur in samples with coarse grain size in the tailings. The highest weight recovery, iron and iron oxide content were obtained in low intensity magnetic separator at a velocity of 1.5 m/s in the cleaner stage that was about 18 and 35%, respectively, with dimensions less than 2 mm, which it has the highest iron and iron oxide separation rates of 46 and 54%, respectively.
