Introduction The Keweenaw Peninsula, located in Michigan's Upper Peninsula, is home to the single largest concentration of native copper deposits in the world. The true size of the deposit is realised in the amount of purified native copper removed. Between 1845 and 1996 when the White Pine mine closed and ended copper mining in Michigan, the …
These deposits do not have the highest grade of copper and usually have higher refining costs. Copper deposit grades are usually expressed as a weight percentage of the total rock. The average grade of copper ores nowadays is below 0.6%. It is estimated that there are 2.8 billion tonnes of copper.

The specific gravity of copper ore ranges from 2.5 to 3.5, depending on the type and mineral content. Copper ore is a good conductor of heat and electricity. Copper ore is not highly reactive, but can react with strong acids and oxidizing agents. Copper ore can range in colour from metallic red to black, depending on the type and mineral content.
