The crusher product is fed to the milling operation for further size reduction. ... Fig 1 Steps in open pit mining of iron ore.

So far, only the study by Norgate and Haque (2010) presented results of the application of Life Cycle Assessment in an iron mine; however, focusing its analysis on impacts related to water and energy consumption and emissions related to global warming. Seeking to fill this gap, this study evaluated the effect of mining activities and cradle-to-gate iron ore …

BHP Billiton had seven iron ore mining operations and the port facilities of Nelson Point and Finucane Island, which are located within the town of Port Hedland. Rio Tinto operates an integrated network of 14 iron ore mines, three port facilities, a 1400 km rail network, and related infrastructure. However, more recently a third operating ...

4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.

Inventory data for these processing stages were calculated by the author. The estimated greenhouse gas emissions were 11.9 kg CO 2 e for mining and processing 1 tonne of iron ore. The embodied energy values were 153 MJ/t ore for iron ore. The results showed that loading and hauling made the largest contributions (approximately 50%) to the total ...
