Iron Ore

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 greenhouse gas emissions from the mining and processing of iron ore.

How does the extraction process of minerals work?

Processing and beneficiation are critical subtopics in the context of the extraction process of minerals. Once the mineral ore has been extracted from the ground, it is not typically in a form that is immediately usable. It often contains a mixture of unwanted substances and materials that need to be separated from the valuable minerals.
