The Copper Country is highly unusual among coppermining districts, because copper is predominantly found in the form of pure copper metal (native copper) rather than the copper oxides or copper sulfides that form the main copper ore at almost every other coppermining district.

Bacteria have been used in the copper and iron mining industries for a long time, especially for the sulfide ores. There's a diagram in the 6th edition (1991) of Biology of Microorganisms by Brock and Madigan, p. 650, of the microbial leaching of copper sulfide minerals.

The only perceived differences between copper and lithium mining by local officials seem to be that the lithium will be produced in some one else's backyard. Copper is mined here in Arizona. Another point to consider, is lithium ion batteries do contain other mined products, such as aluminum and copper.

Microorganisms used for metal extraction from sulfide materials are chemolithoautotrophic bacteria and therefore only inorganic compounds are required for growth. In general the mineral nutrients are obtained from the environment and from the material to be leached.

Copper is soft and able to transmit electricity and heat very effectively. It can't really be damaged by water and is widely used in construction. Because bacteria can't grow on it, copper is also used in hospitals. During the Stone Age and Copper Age, copper was used for tools and jewelry.
