  • Gold Extraction & Recovery Processes

    Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 10282 Shaking table for gold extraction process Working process: A shaking table is used to process gold ores in the horizontal medium flow The motor drives the surface of the shaker to perform the longitudinal reciprocating motion, as well as the differential motion of the washing stream and the surface of the bed5 Gold Extraction Methods to Improve Your Recovery RateGold Extraction from Mines Gold and silver are both extracted from the mines using the cyanidation process This process is achieved by dissolving gold or silver in either a potassium cyanide or sodium cyanide solution Mining companies also incorporate the use of a technical extraction process in the extraction of goldHow gold is extracted by Cyanidation Process Refresh
