EFFECTIVE PROCESSING OF LOW-GRADE IRON ORE

Thus, beneficiating the low-grade iron ores to remove the gangue minerals and enhancing their grade is an attractive proposition today. Among the known iron deposits in Sudan, many are of low-grade which require beneficiation to produce an acceptable feed for steel making plants. Wadi Halfa iron ore, in Northern Sudan, is one of these types.
