Gold Extraction & Recovery Processes

Process DevelopmentSelecting A ProcessGold RecoveryAmalgamationFlotationLeachingConsidering the different gold minerals present alone or combined with the host rock, it will be necessary to discharge the unwanted material in order to increase the concentration of gold in an economically manner. This part treats the strategy of beneficiation as a combination of several processes. 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 challenge...

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer miningsuch as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes.

Extraction of Gold

Gold Chemical Extraction-processes. Plattner's Chlorination-process Bromine acts more energetically than chlorine, and has also been employed in the extraction. The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine.

CA2245101C Gold extraction process Google Patents

There is described a process for the extraction of gold from a graphite or carbonaceous ore wherein the ore is ground in general mill solution with kerosene to 85% 350 mesh and then the gold is extracted in a CIP (carbon in pulp), CIL (carbon in leach) or CIC (carbon in column) gold milling operation.
