diagram of gold mining processing gold mining was first carried out in alluvial areas. processing system is also very simple to do that is by panning using a tray, which then developed with gold mining wave table, and followed by gravity separation method using the amalgamation process with the capture of mercury.
information on gold carbon in leach plants . it has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject.
once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. one is the merrill crowe zinc precipitation process and the other is the adsorption of the gold onto activated carbon. the oldest method, merrill
