The present paper considers aspects of underground iron ore mining in Ukraine, particular the level mine production and reserves basic fields. It analyzes generalizes practice using cemented rockfill under difficult hydrogeological conditions Pivdenno-Bilozerske high-grade field. Belozersky district is only one Ukraine that, without any technological cycle beneficiation, can provide both domest...

Pyrite cinders, which are the waste products of sulphuric acid manufacturing plants, contain hazardous heavy metals with potential environmental risks for disposal. In this study, the potential use of pyrite cinders (PyCs) as iron source in the production of Portland cement clinker was demonstrated at the industrial scale. The chemical and mineralogical analyses of the PyC sample used in this s...

On 24 May 2020, Rio Tinto detonated an area of the Juukan Gorge in Pilbara Western Australia as part its iron ore mining operations, damaging two ancient rock shelters with profound cultural significance to Puutu Kunti Kurrama and Pinikura (PKKP) People. 1 The incident has brought international attention importance Indigenous heritage within broader environmental, social governance (ESG) consid...

Recovery of iron from iron-rich diasporic bauxite ore via reductive roasting followed by magnetic separation has been explored recently. However, the efficiency of alumina extraction in the non-magnetic materials is absent. In this paper, a further study on the digestion of alumina by the Bayer process from non-magnetic material obtained after magnetic separation of reduced iron-rich diasporic ...

Two texturally and mineralogically distinct types of Mississippi Valley-type mineralization are hosted by the upper Cambrian Metaline Formation in northeastern Washington. Josephine-type mineralization is iron poor and coarse grained, whereas Yellowhead-type mineralization is iron rich, fine grained, and commonly botryoidal. Josephine mineralization is found largely in the Josephine lithofacies...
