Ore Dilution Recovery in Mining

Recovery and dilution usually are interrelated with some methods of stoping a high recovery involves contamination of the ore from the walls or capping and often clean ore can be obtained only by leaving some ore in the mine In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall
