  • 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 openstope 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 considerablyAug 24, 2020· Nexa Vazante, a zinc and lead mine owned by Nexa Resources, is located in northwest Minas Gerais, Brazil Using vertical retreat mining (VRM) and long hole open stope as the main methods for ore extraction, the mine has traditionally deployed wired initiators in the recovery of ore, typically yielding around 60% ore recovery in the pillarsNexa Resources improves safety and ore recovery with Orica
