Gold mine tailings, the treasure place of recovery gold

Due to its high recovery value, treatment and recovery of gold tailings are ahead of other minerals both in technology and promotion. Gold mine tailings reprocessing needs to go through two steps: first of all, we need to extract gold from the tailings pulp; then,tailings dry stacking, it means the solid-liquid separation of tailings pulp.

Hazardous Properties. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and
