A Life Cycle Assessment study of iron ore mining

Dec 01, 2015 Iron ore surface mining product system2.1. Case study. This paper presents a survey of environmental aspects and impacts related to the iron ore life cycle based on primary data of the process used by Samarco Mineração in its plant in Germano, Iron Quadrangle/Brazil.

Life cycle assessment of iron ore mining and processing

Jan 01, 2015 The life cycle-based GHG emissions have been estimated for iron ore, bauxite ore, and copper concentrate and published (Norgate and Haque, 2010) showing the contributions from the various unit processes of the mining and mineral processing stages. Part of this latter study has been modified for this book chapter.

A Life Cycle Assessment study of iron ore mining

This paper assessed the cradle-to-gate life cycle of an iron ore mining. The study was based on production data from an open pit mine located in the Iron Quadrangle/Brazil.

Analysis of life-cycle GHG emissions for iron ore mining

Oct 01, 2018 In this study, a life-cycle model for mining and processing of Chinese iron ores is developed and used to estimate GHG emissions. Results show that the mean life-cycle GHG emissions for Chinese iron ore production are 270 kg CO 2 e/tonne, with a 90% confidence interval ranging from 210 to 380 kg CO 2 e/tonne. The two largest contributors to

Environmental impact of iron ore mining Wikipedia

Introduction Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)·n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is
