Method Of Gold Metal Revery In Ore

  • Gold Extraction Recovery Processes

      Some of the metallurgical relationships that must be considered from the testwork program as follows: ore grade relationship to gold recovery, crushing and grinding parameters and their relationship to the ore variability in the ore   Placer gold ore with high gold content mostly exists in the form of particles Therefore, the ideal method to process placer gold ore is gravity separation Rock gold ores have a more complex composition than placer gold ores’, thus whether to choose gravity separation and flotation separation depends on the specific composition5 Gold Extraction Methods to Improve Your Recovery Rate   Gold recovery using this technique is pH sensitive, and five pH values (20, 36, 40, 54, and 60) were investigated FA analysis showed the Shanono gold ore deposit contains an average of 471 ppm of gold, AAS analysis showed highest gold recovery of 69% at pH 40, which is lower than recoveries from the metal scrapsRecovery of Gold from Shanono Gold Ore Deposit Using α
