As for the gold tailings cyaniding, xinhai will apply the method of dry tailing stacking. That is, though the process of classifying and dewatering, at the same recycling the water recourses to remove the cyanide in it. Moreover, xinhai will use magnetic separation and gravity separation to remove the iron.

Tailings

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed The extraction of minerals from ore can be done two ways placer mining, which uses water
