  • Gold Recovery And How To Choose The Right Process

    Panning for gold can be great fun but is not very practical for gold recovery on a large scale The most costeffective gold recovery solution for placer deposits is using a gravity concentration circuit First, the material is screened to remove large rocks and boulders Then a sluice or jig is used to recover the gold For deposits with high clay content, the rocks are cleaned with a trommel or rotary scrubber toMetallurgical ContentHow to Recover Gold from Placers in MiningMethods of Washing the Gravel with PanBatea PanProspecting ThroughGold Cradle or Rocker BoxLong Tom Gold SluiceThe PuddlingtubGold CradleSiberian TroughGold SluiceSluice Mudbox & GrizzlyUsing Mercury in SluicingCleaning a Sluice Box from its GoldTail RaceGround SluiceBoomingDryBlowingGold Flycatchers The goldPlacer Gold Mining Methods Mineral Processing &· 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
