Gravity Concentration GekkoDry washing for Gold

The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer For example complex gold in a sulphide complex of pyrite must isolate a specific gravity of 193 for gold from 52 for pyriteGold concentrations in and between flood layers can happen even more in the desert This is because of the flash floods which can occur there Sometimes substantial gold concentrations can be found just beneath boulders which rest upon bedrock or up in a layer above bedrock
