goethite iron ore and its percentages - vdnw.ch
Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle iron ore") but is more typically massive.

Goethite - an overview | ScienceDirect Topics
2020-7-17 · Goethite is the most common of the iron oxyhydroxides and is antiferromagnetic with a disordering (Néel) temperature of about 120°C (Hedley, 1971 ). Goethite has weak saturation magnetization and very high coercivity ( Hedley, 1971; Rochette and Fillion, 1989 ). It dehydrates to hematite at about 300°C.
