Introductory Chapter: Extraction Metallurgy – New …
For example, investigating the use of bioleaching to extract copper from its ore is proving to be an efficient process by using microorganisms to break down the sulfide minerals in copper ore [15, 16]. This process might prove to be more environmentally friendly than traditional smelting as it produces fewer emissions and requires less energy.
