Types of Iron Ore

02/11/2018 · The following is an introduction to these four types of iron ore, magnetite, hematite, limonite and siderite. Iron ore property. Iron is widely distributed in nature (the crust), but since iron is easily combined with other elements to form various iron minerals (compounds), there is little natural pure iron in the earth's crust.

Mineral Liberation

Liberation is typically divided into egories based on 10% subdivisions of the area percent occurrence of a mineral of interest (for instance, hematite) within a particle. Thus, particles are separated into 0–10%, 10–20%, 20–30%, etc., egories and plotted on 3D charts with size fractions, liberation egories, and their weighting ...

ISSUES RELATING TO CHARACTERIZATION AND BENEFICIATION .

hematite and magnetite are the dominant mineral species. The quantitative mineralogy and hematite liberation of a typical hematite bearing sample is shown in Table 2. Hematite liberation is calculated to be about 87% at 53+ micron size. The contents of free hematite particles in general increase with decrease in particle size.
