Economic Feasibility Study - Dig Into Mining pdf

What is copper ore? Once a concentration of copper bearing minerals are discovered in Earth's crust and it is determined to be profitable to extract the copper, the rock material to be mined from the copper deposit is referred to as copper ore. There are two basic methods of mining the copper ore: surface or open-pit mining.

Earth Economics Report - Nautilus Minerals pdf

The 20th century was characterized by steep increases in copper production and steep declines in copper ore concentrations.
