01 Gold mines gravity separation technology. As one of the main beneficiation technologies for gold mines, gravity separation has the advantages of no pollution, low production cost, and wide application range. The density of gold is generally greater than 16t/m³, which is quite different from the density of gangue minerals.

A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low grade and high grade which helps determine the most economical and optimal gold recovery method. Low Grade.
