Gold mining Wikipedia
Gold mining is the extraction of gold by mining World gold production was 3,612 tons in 2022 Nubian mining expanded under Egyptian occupation with the invention of the grinding mill Bronze Age gold objects were also plentiful, especially in Ireland and Spain, and there are several well known possible sourcesOf the numerous major gold mining operations around the world, most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed ratesGold extraction QueensMineDesignWiki
