WebApr 14, 2024 · The study found that semiconducting minerals, such as iron oxide, sulfide minerals (hematite, goethite, and pyrrhotite), and titanium oxide minerals (rutile and anatase), were widely present in the suspended particulate matter. This discovery highlights the photochemical activity of suspended particulate matter in the euphotic zone. WebSep 24, 2024 · The goethite is a common mineral in iron ores. The most commonly used iron-bearing minerals are hematite (70%Fe) and magnetite (72.4%Fe) in agglomeration techniques or in iron-making units. However, a huge amount of unused goethite ore is available in India [ 1 ].
