Gravity separation has been suggested as an alternative to the use of mercury. However, many sites have pyrite and/or chalcopyrite. The gold is embedded in the ore in very fine particle sizes. That is not amenable to grinding using ball mills followed by gravity separation methods such as sluices or cyclonic concentrations.
