the size of the leaching plant that would be required as well as reduces the amount of leaching reagents required. Many gold plants use conventional thickening with flocculant addition. High rate thickeners, as well as de-watering systems that use cyclones only or cyclones and high-rate thickeners can also be used in principle.
Oct 20, 2014· Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises over-grinding and prevents losses due to excessive comminution, and during multiple processing steps.
Nov 26, 2019· The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
