The environmental impacts considered in the study were embodied energy and greenhouse gas (GHG) emissions, while the functional unit was 1 ... With this objective in mind, LCA of the mining and mineral processing of …

Bauxite is the main source for alumina production. With the rapid development of iron and steel industry and aluminum industry, high-quality iron ore and bauxite resources become increasingly tense. However, a lot of iron-rich bauxite and Bayer red mud resources have not been timely and effectively recycled, resulting in serious …

The environmental impacts considered in the study were embodied energy and greenhouse gas emissions, while the functional unit was 1 tonne of iron ore, ready for transport to downstream metal extraction and refining facilities. ... With this objective in mind, LCA of the mining and mineral processing of iron ore was carried out in …

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical …

Liberia is endowed with an impressive stock of mineral reserves and has traditionally relied on mining, namely iron ore, gold, and diamonds, as a major source of income. The recent growth in the mining sector has the potential to contribute significantly to employment, income generation, and infrastructure development. However, the …
