(2010) carried out a mine-to-gate LCA of an iron ore mine, and found that to produce 1kg or iron ore 11.9kg CO 2 Eq. was emitted, with the greatest impacts associated with the loading and hauling stage. Ferreira and Leite (2015) also carried out a LCA for iron ore production from Brazil. This study examined the environmental costs of producing iron
"The new reserve estimate indicates that Metalloinvest has become the world leader in terms of the size and life cycle of iron ore reserves among all mining and metallurgical companies. Over the 11 years since the previous assessment of reserves, our enterprises have produced around 1.7 billion t of iron ore.
Life Cycle Assessment (LCA) connects all sectors of a commodity/system/process (Khasreen et al. 2009).The International Organization for Standardization (ISO)-standardized LCA allows the consideration of environmental effects resulting from all phases in the life cycle of an outcome, often including effects that are not pondered in more long-established studies such …
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. The functional unit was defined as "one tonne of iron ore concentrate produced" and the data used were collected directly from the company's production reports covering the time of one year. The evaluation …

For banded iron formation-hosted deposits accurate boundary modelling is critical to ore-grade estimation. Key to estimation fidelity is the accurate separation of the different domains within the ...
Specifically, the LCA models cover life cycle stages from mining, comminution, processing, refining and transport, as shown in Figure 2. Co-products were excluded from this study, so no allocation method was applied. ... (11.62%). For the production of one ton LCE from the Zinnwald project in Germany, the total GWP mainly results from the use ...
This study offered a preliminary understanding of the project's economics. Using this study, the company needed to secure enough money to build a mine to extract the valuable ore. It was not until two years later, when Ivanhoe Mines entered into an agreement with major mining company Rio Tinto, that a production decision was finalized.
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. The functional unit was defined as "one tonne of iron ore concentrate produced" and the data used were collected directly from the company's production reports covering the time of one year.
