This review examined the flotation characteristics of a high grade >98 % Fe 2 O 3 specular hematite from a local source and a hematite ore containing 57 % Fe 2 O 3 using oleic acid The maximum recovery of the specular hematite occurred at neutral pH and the highest hematite grades were obtained at pH 5 6 for low additions of oleic acid rising to pH 9 10 as the amount of collector was increased

Outcomes of flotation tests at the different flotation scales demonstrated that hematite depression by SCS is around % higher than by SS Based on flotation experiment outcomes it was concluded that SCS can modify the pH of the process at and the plant reagents including NaOH Na2CO3 and SS gel can be replaced by just SCS which can also lead to a higher efficiency in the plant
