Within the state of michigan, copper is found almost exclusively in the western portion of the upper peninsula, in an area known as the copper country.the copper country is highly unusual among copper-mining 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 copper ore at almost every mining.
Copper: the mineral native copper information and picture
Copper: properties and applications. the word copper comes from the latin word ‘cuprum’, which means ‘ore of cyprus’. this is why the chemical symbol for copper is cu. copper has many extremely useful properties, including: good electrical conductivity; good thermal conductivity mining.
Copper has several important properties that make it incredibly useful: antimicrobial – copper has what’s known as an oligodynamic effect on bacteria. basically, it kills microbes. scientists aren’t sure exactly how or why this happens, but they know that it definitely does work. in fact, this is important when hospitals are made, as they mining.
