Understanding the effects of goethitic iron ore - Process productivityApr 19, 2017 . Currently, most analysis of the effects of goethite on mine performance considers only the chemistry of the ore and not its textural components. Through improved textural classification of goethitic ores we can reframe the perceptions the industry has of goethite, and optimise overall processing performance.Iron ore classification and the future of resource development .Compared with hematite and magnetite, goethite has a more diverse range of textural forms and occurrences, and its influence on iron ore processing is less well understood. Currently, most analysis of the effects of goethite on mine performance considers only the chemistry of the ore and not its textural components.
