Ore Dilution amp Recovery in Mining

Apr 05, 2017 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.

Notes: Recovery rate is the final result of mineral dressing test, and the core of dressing plant construction. Every 1% reduction of recovery rate cause huge losses, especially in gold, silver mine, so the purpose of mineral dressing test is to get the recovery rate as high as possible in order to reduce the loss of clients.

Estimating process design gold extraction leach residence

Estimating process design gold extraction leach residence

May 01, 2015 Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropriate for ores that deplete cyanide …
