  • Goethite | mineral | Britannica

    In terms of relative abundance, goethite is second only to hematite (αFe 2 O 3) among iron oxidesGoethite is normally formed under oxidizing conditions as a weathering product of iron minerals (eg, pyrite, magnetite)Because it is formed near the surface, goethite is the major component of the gossan of iron sulfide deposits in locations such as Arizona and of lateritic deposits in placesGoethite present in iron ore deposits affects how your mine manages the handling and processing of ore Failing to understand how the different textural composition of goethite impacts processing performance can lead to downtime and reduced mine efficiency Textural classification allows mines to better predict where different types of goethite are present, allowing blending processes to beUnderstanding the effects of goethitic iron ore Process
