recovering and refining gold can be both difficult and costly – particularly when the grade or concentration of gold in a deposit is low. however, even when the concentration of gold is so low that it's invisible to the naked eye, this precious metal can be recovered safely and economically through chemical processing. cyanide processing and management facilities at newmont's boddington
cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore. cyanide leaching is considered to be a much safer alternative to extraction with liquid mercury, which was previously the main method of removing gold from ore.
pure gold (99,9 %) is obtained after refining. the most significant risk from use of cyanide solutions in gold mining is possible leakage into soil and groundwater

elution & carbon reactivation 4444 introduction during the cil process, gold is leached from the ore using an alkaline cyanide solution. the resulting gold cyanide complex ions are then concentrated and separated from the slurry by
electrowinning for gold mining. electrowinning is an electrochemical process used to reduce the metal cations to the cathode surface of an aqueous solution derived
a process for purifying and refining gold to 98+% purity is dislosed. the gold to be refined is made the anode in an electrolytic cell with a solution of ammonium chloride as the electrolyte. the purified gold is collected in anode bags and the non gold impurities including silver are dissolved in the electrolyte. the silver is complexed with the ammonium ion in the electrolyte.
