Hydraulic Gold Mining Process

The process of moving the slurry is called sluicing. Educing is the process of introducing the slurry into an enclosed circuit. In the hydraulic mining of gold the rebounding stream of water and mineral fragments is directed into sluices in which the gold settles behind baffles but the lighter waste matter is washed away. In hydraulic mining of ...
