Igneous rocks form from the cooling of magma - molten materials in the earth's crust The terminology Igneous means fire or heat In this sense, igneous rocks are formed when molten rock (magma) solidifies either underneath the earth crust to form plutonic (intrusive) igneous rocks or on the surface of the earth to form volcanic (extrusive) igneous rocks.
Copper minerals and ores are found in both igneous and sedimentary rocks Mining of copper ores is carried out using one of two methods Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.
