Underground Preconcentration by Ore Sorting and Coarse

preconcentration underground in a narrow-vein mining situation. These include • Reduction in total comminution energy requirements (lower carbon footprint) as some of the waste is removed at a coarser size early in the process route. • Reduction in tramming and hauling costs both underground and prior to surface processing due to lower

Underground Mining Methods of Copper

2. Mining MethodsCopper

Open pit mining is a technique used to extract copper ore near the earth s 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 earth s surface. Underground mining is used when the copper ore is not near the earth s
