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 mining - Wikipedia

Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.
