Metal Extraction and Environmental Impact

Metals are extracted from metal ores mined from the Earth. Metal extraction and production provide

essential materials and employment in mining, production, transport,

and sales. The exportation of metal ores from Australia substantially contributes to our

economy. However, benefits must be considered against the costs associated

with obtained the raw materials and the energy requirements. Mine waste has caused substantial damage

to the environment. There are two main forms of mining:  Open-cut  Underground

The choice of method depends on:  Type of ore  How deep underground the ore is situated

 The cost of extraction Metal ores are rocks containing minerals from which a valuable metal can be removed.
