open cast mining of copper ore

Open pit mining is a technique used to extract copper ore near the earths surface Open pit mining is the most widely used technique of mining copper today It is accomplished by creating and using benches or terraces to gradually reach deeper under the earths surface Underground mining is used when the copper ore is not near the earths surface
