  • 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 The amount of ore thus left varies considerably.
