| Abstract | ||
| Attempt has been made in the research and development laboratories of the State Company of Geological Survey and Mining to develop a process based on segregation roasting technique as an alternative approach to beneficiate Al-Hussainiyat low grade iron ore. The process comprises, segregation roasting in the presence of coke and alkali chloride followed by screening and wet low intensity magnetic separation, to separate the iron from the associated gangue. Various parameters including roasting temperature, roasting time, amount of alkali chloride, and ore particle size were studied. Under optimum conditions, a concentrate assaying 86% FeT and 2.6 % I.R (SiO2 + Al2O3) could be achieved with a recovery of about 64 % FeT. These results appear promising for the current work, and a process in the field can be developed. | ||
