Iron ore (fines) - Cargo Handbook - the world's largest ...

The mineral magnetite (Fe 3 O 4) is a naturally occurring metallic mineral that is occasionally found in sufficient quantities to be an ore of iron. The principle ores of iron are Hematite, (70% iron) and Magnetite, (72% iron). Taconite is a low-grade iron ore, containing up to 30% Magnetite and Hematite. Hematite is Iron Oxide (Fe 2 O 3). The amount of hematite needed in any deposit to make it profitable to mine .

Amine Flotation of Feldspar from Magnetite Concentrate

The amine flotation of feldspar from magnetite concentrate was investigated using zeta potential measurements, Hallimond tube flotation tests and laboratory-scale flotation tests. The zeta potential of various feldspars (microcline, albite, anorthite, oligoclase and anorthoclase) were determined as a function of pH; the point of zero charge ranged from pH 1.4 to 2.5.
