Tailings Treatment and Reclamation

Graymont can assist customers to treat tailings pond materials and discharge waters thus improving the handling and reuse options of both solids and liquids.

Where tailings contain fine particles or clay, lime products can be used to improve dewatering and recoverable process water. This treatment can also result in improved handling, material strength and a stackable tailings product that can be used in landform reclamation.

These benefits can be obtained by using the right mix of lime treatment coupled with other technologies leading to a cost-effective faster pathway for reclamation outcomes. Lime treatment will also immobilize contaminants such as heavy metals and in some cases organic compounds in discharge waters and neutralize any acid mine drainage (AMD) present. 

Graymont has significant technical expertise and can assist customers to unlock substantial value in tailings treatment and reclamation.  For more information see the additional resources below or contact our sales team.
