Adding value to iron ore, at a cost: Australia's magnetite …
The $8 billion Sino Iron project—perhaps the biggest "soap opera" in Australian iron ore history, with long running legal cases, massive cost over-runs, the booting out of Chinese contractors and major delays; Jupiter Mines' Mt Ida project—scrapped due to "depressed iron ore prices"
Magnetite
How is magnetite processed? As magnetite ore has lower iron content it must be upgraded to make it suitable for steelmaking. Magnetite requires crushing, screening, grinding, magnetic separation, filtering and drying. The final product is a high iron grade magnetite concentrate (+65% Fe), with typically very low impurities.

Iron processing
Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and …

Overview
The iron ore deposits in the Labrador City area occur as specular hematite and magnetite, generally in the ratio of 65:35. IOC has mineral reserves and resources of 1.1 billion tonnes and 1.7 billion tonnes, respectively, with an average grade of approximately 38% iron.
(PDF) Grinding Media in Ball Mills-A Review
One of the most used tumbling mills is the ball mill. This paper reviews different types of grinding media that have been developed and improved over the years and their properties.
Types of Mining Magnetic Separators
Common Iron Minerals are magnetite (strong magnetic minerals), hematite (weak magnetic minerals), Limonite, specularite, siderite (all weak magnetic minerals). They are raw materials for the steel industry. The iron ore grade is low, many impurities. Therefore 80% above iron minerals need magnetic separation.
