Iron ore fine particle aggregation method in iron ore suspension mud, recovery method, and sintered ore production method using recovered iron ore

摘要

PROBLEM TO BE SOLVED: To provide a method where iron ore fine particles in iron ore suspended slude water are flocculated and settled, and are easily and efficiently recovered, and sintered ore is produced using the recovered iron ore fine particles.SOLUTION: Provided is a method for flocculating iron ore fine particles in iron ore suspended sludge water being the one where iron roe fine particles in iron ore suspended slude water are flocculated, in which, after the iron ore suspended sludge water is heated at T°C(70≤T100) for F(=2100/T) min or more, staying is performed, thus the iron ore fine particles are flocculated-settled.SELECTED DRAWING: Figure 1
