Gold extraction - Wikipedia
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 and is recovered as a by-product during production of the base metal.
