[QUOTE="Swinging & digging, post: 593005, member: 2764"] From a hobbyist perspective the main recovery methods for fine gold are via a sluice gravity separation system. There are many variations to systems used and gold recovery rates would vary to a degree. Also feed rate and wether clay is present in the wash would effect potential recovery. Some alluvial gold is very flat and more difficult to recover. I would suspect that an average system would recover say 85% of the fine gold down to 60 mesh. Some people have better success with more modern recovery mats like dream mat but remember classifying material and feed rates etc all effect overall recovery. There will be losses to some degree of the finer gold if present, and they may not be off concern, loosing 0.1 of a gram while recovering 0.8 of a gram is still a success for an average hobbyist.
