beneficiated iron ore

beneficiated ore definition - Law Insider

beneficiated ore means iron ore that has been concentrated or upgraded (otherwise than solely by crushing, screening, separating by hydrocycloning or a similar technology which uses primarily size as a criterion, washing, scrubbing, trommelling or drying or by a combination of 2 or more of those processes) by the Company in a plant constructed pursuant to a proposal approved pursuant to an ...

Ore Beneficiation - an overview ScienceDirect Topics

Microbially induced iron ore formation has been confirmed at Gunma iron ore mine, Japan [21]. Ubiquitous microorganisms inhabiting iron ore deposits are useful in iron ore beneficiation (e.g., removal of alkalis, silica, clays, phosphorous, and alumina). Because the presence of phosphorous in the iron ore promotes bacterial growth (as an energy ...
