Iron ore tumble test fines were received from two processing facilities in the Midwest United States (Plant A and Plant D). Each sample (11 liter container) was screened at 28 mesh (Tyler series, 0.6 mm openings) to remove the broken chips. The − 28 mesh portion was split using a 12-segment rotary sample splitter.

Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard …
