goethite as well as hematite. The intensity of hematite peaks increased as the ore was treated with bacterial consortia in anaerobic condition. A small percentage of magnetite peaks was observed in the O2. The bacteria acts as a reducing agent and converts the goethite to hematite and magnetite. Such peaks were ower n the ntensty in O1.

(Figure1). Goethite is another important iron bearing mineral in the samples. Goethite is of two types, viz., vitreous and ochreous. Vitreous goethite is hard and compact; earthy goethite is fine grained and friable in nature. Goethite replaces martite and hematite in varying degrees viz., from incipient to

Real-time monitoring of goethite content can be used for e.g. effective ore blending. On-line control of the content of soft minerals in the run-of-mine will improve efficiency of beneficiation processes, prevent possible equipment blockage and other common issues associated with the presence of large quantities of soft minerals in the ore.

Abstract Pollution of water resources by acid mine drainage (AMD) has been an issue of primary concern in recent decades. This is rooted to the fact that AMD negatively affects the environment and its suitability to foster life. As such, efforts to recover, valorise and beneficiate minerals acquired from AMD treatment process have been ongoing, albeit with minimal success.

The decomposition of goethite involves removal of hydrogen and one quarter of the oxygen, without disturbing the network of remaining oxygen, and atomic rearrangement of Fe 3+ to form hematite. Das et al. [] mentioned that in goethite structure, an aluminum (Al 3+) partly replaces the central Fe 3+ cation.It has been reported that up to 33% of the iron atoms can be replaced by …

Abstract. The effect of mineralogy and texture on the beneficiation of goethitic ores from two different origins is highlighted. Sample A having 54.47% Fe with 8.57% loss of ignition (LOI) indicates the presence of vitreous and ochreous goethite, martite and microplaty hematite as the major minerals. Sample B contains 56.90% Fe with 14.4% LOI.

The importance of mineralogy and petrology on the beneficiation of iron oxide ores, primarily those containing goethite, in Proceedings Iron Ore 2017, pp 233–240 (The Australasian Institute of Mining and Metallurgy: Melbourne).

Iron is a primary raw material for steel industry. Increase in demand for steel puts pressure on iron resources of India in respect of its grade and reserve. With increase in demand for good grade of ore vis-a-vis its limited reserve, the utilization of low to medium grade iron ores is the order of the day with adoption of advanced beneficiation techniques.

The rate of transformation of two-line ferrihydrite to hematite increased with increasing temperature at all pHs studied and followed first-order reaction kinetics. XRD and XANES showed simultaneous formation of goethite and hematite at 50 and 75 °C at pH 10, with hematite being the dominant product at all pHs and temperatures.
