yet, dry methods do work well enough that they can produce gold well if the ground is rich enough. recent developments in dry washing equipment have made it possible for a one or two-man operation to work larger volumes of dry placer ground without water, and obtain good results in gold recovery.
gold cil carbon in leach process is an efficient design of extracting and recovering gold from its ore. by cyaniding and carbon leaching crushed gold ore slurry simultaneously, cil process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
each step is much more work and yields diminishing returns. it is also possible to crush too small and create slimes minus 200 mesh so fine that gravity methods cannot recover the gold within them. so, with every ore and equipment set up there is an optimum size range of crushing that will yield good gold and not require excessive work.
