BENEFICIATION OF LOW/OFF GRADE IRON ORE: A REVIEW

for the beneficiation of iron ore, nearly 90% of ores are concentrated by this method Ryan 1991 Table 1. Approximately 20-35% of all the unit of iron lost their value by magnetic separation, because hematite ore of iron is weakly magnetic response. The Magnetic separation can be processed in both dry as well
