Processing – Karara Mining Limited
Until recently the Australian iron ore industry has been based on the mining of high-grade hematite ore which accounts for approximately 96% of Australia's iron ore production. High-grade hematite is often referred to as "Direct Shipping Ore" or "DSO" because it is mined using a relatively simple crushing and screening process before ...

Iron ore beneficiation: an overview
The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and agglomerated pellets (Iron and …

Iron (Fe) Ore | Minerals, Occurrence » Geology Science
Description and properties of common iron ore minerals. Iron ore minerals are rocks or minerals that contain iron in concentrations high enough to be economically extracted. Common iron ore minerals include: Hematite (Fe2O3): Hematite is the most abundant and important iron ore mineral. It is typically steel-gray to black in color and has a metallic luster.

Comminution and classification technologies of iron ore
Hematite and magnetite, the two predominant iron ores, require different processing routes. High-grade hematite direct shipping ores generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products.

Desulfurization Mechanism of Lead–Zinc-Bearing Hematite–Limonite Ore
The impurity sulfur in lead–zinc-bearing hematite–limonite ore mainly exists in the form of galena, sphalerite, pyrite, and natural sulfur, and deep reduction roasting–low intensity magnetic separation does not effectively remove sulfur in a low valence state, which affects the quality of iron ore concentrate. Thereby, the desulfurization mechanism of the oxidative …
