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

Pressure oxidation Wikipedia

Pressure Oxidation is a process for extracting gold from refractory ore The most common refractory ores are pyrite and arsenopyrite which are sulfide ores that trap the gold within them Refractory ores require pre treatment before the gold can be adequately extracted The pressure oxidation process is used to prepare such ores for conventional gold extraction processes such as cyanidation
