Apr 25, 2017 · With a minimum of equipment, the beginner gold prospector can separate gold flakes and nuggets from the surrounding strata in a nearby stream. The supply of gold is virtually endless, as erosion constantly causes hidden gold to be brought to the surface where it is free for the taking. All you have to do is find it.
Joining together these units make possible to develop an appropriate flowsheet whose objective is to recover gold and the precious metals present in the ore. Perhaps, one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit.
