Alluvial Placer Gold Machine
To summarize, we can separate gold ore into two categories: alluvial /placer gold and rock gold. For rock gold,roughly,the gravity separating flow goes like : crushing–>milling—->gold centrifugal—-> sluice box —>shaking table .For alluvial gold with sticky mud or clay, the flowchart flow goes like feeding—> gold trommel —> gravity mineral separators like …

Gold
of gold found naturally is isotope Au-197. 28 other isotopes can be produced artificially and are all radioactive. Sea water contains around 3 parts in a billion of gold, but there's never been found an economic means of recovering it. The Germans tried very hard during the second World War but failed miserably.

Enigma of Alluvial Gold Mining in Pre-Contact Peru—The Present …
Industrial amounts of gold are produced in only two ways: 1) gravity separation/mercury (amalgamation), and 2) cyanide. Therefore, an understanding of present-day gold mining methods is key to understanding gold mining in the past. For example, in 2018, Peru's large-scale open-pit gold mines produced 123,767 kg of gold using cyanide and ...
