Four Australian mine sites (i.e., Brockman, Paraburdoo, Hopes Down, and Yandicoogina) were chosen for this analysis to derive representative information for the iron ore mining and processing operations in Australia. These mine sites were chosen as they range from small to large iron ore mine sites in terms of production capacity.

Mining - Wikipedia
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

A Life Cycle Assessment study of iron ore mining ...
This stone 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 companys production reports covering the time of one year.

Smelting: This process involves melting concentrate to extract metals like zinc, copper or precious metals from ore. 5. Lifecycle of a mine: Project closure and rehabilitation
Mines and Mining | Lets Talk Science
In both surface and underground mines, rock that contains the ore is blasted into pieces small enough to be loaded onto trucks. The ore is then transported to the mill. A mill is a type of processing plant where the ore is crushed. Valuable minerals are then separated out from the non-valuable rock. Mine Life Cycle. There are many stages to mining.
Environment and Climate Change Canada - Acts & …
The Environmental Code of Practice for Metal Mines describes operational activities and associated environmental concerns of this industrial sector. The document applies to the complete life cycle of mining, from exploration to mine closure, and environmental management practices are recommended to mitigate the identified environmental concerns.
Life Cycle Assessment of Metals: A Scientific …
7-7-2014 · Graph nodes represent the stone form in which an element is present during each life cycle stage (i.e., ore, concentrate, intermediate, metal), while edges connecting two nodes indicate the physical transformation taking place as metals move through subsequent production steps.
Life Cycle Assessment of Metals: A Scientific …
We have assembled extensive information on the cradle-to-gate environmental burdens of 63 metals in their major use forms, and illustrated the interconnectedness of metal production systems. Related cumulative energy use, global warming potential, human health implications and ecosystem damage are estimated by metal life cycle stage (i.e., mining, purification, and refining).
