Here, further separation occurs as silica is removed in the froth overflow through a process known as amine flotation, producing a highgrade iron ore concentrate. ProcessingGeneral After the material has been concentrated using the magnetic or flotation process, dewatering begins as the material is thickened in large settling tanks.

Iron ore

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

In this process, ore fines and coal are manipulated to melt iron ore. In 1993, the process could produce eight tons of iron ore per hour using ore directly in the smelter. Process modifiions are expected to increase the efficiency to 14 tons per hour. Commercial feasibility studies were performed in 1995.
