ore | mining | Britannica

The desired metallic element is then extracted from the ore by various smelting, roasting, or leaching processes. Advances in hydrometallurgy have meant that some metals—such as copper, uranium, and gold—can be removed from the host rock without drilling and blasting. Special bacteria are sometimes used as part of this process.

A Life Cycle Assessment study of iron ore mining - ScienceDirect

This is particularly true for operations with iron ore, where existing studies show the mining processes reduced to a step within the steel production system (Li et al., 2002, Norgate et al., 2007, Bieda, 2012). There are few studies on the application of LCA to specific mining systems (Awuah-Offei and Adekpedjou, 2011, Blengini et al., 2012.).
