SILVER & GOLD MINE NEEDS WATER TREATMENT TO REMOVE POISONOUS CYANIDE

Wastewater treatment plant

for silver and gold mine

27 April 2011

Crown Solutions, a Veolia Water Solutions & Technologies company, will supply the initial equipment for a new water treatment plant (WTP) based in a silver and gold mine in Mexico.

The Palmarejo Mine is based in the Sierra Madre Occidental Mountains of northwestern Mexico and is owned by Coeur D’Alene Mines, Idaho USA. The owners want to improve internal water balance so that water can be recycled from the tailings pond back to the mill.
The treatment plant will include two trains of Crown Solution’s ACTIFLO clarifier and Hydrotech Discfilters. The process also includes chemical feed systems and mixing/reaction tanks. The treatment solution is designed to get rid of residual cyanide and remove total suspended solids and metals and filter the water that is recycled back to the mill.
The Palmarejo Mine will also use the services of Veolia Water Solutions & Technologies Mexico for operational support. The new WTP is scheduled to be commissioned in mid-2011.
