      OverviewContentsHistoryTypes of oreConcentrationLeachingRefractory lead processesGold extraction refers to the processes required to extract lead 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 mining such as simple lead panning and sluicing, resulting in direct recovery of small lead nuggets and flakes.
