N° and MACHINERY MODEL EMPLOYED: 3 GHT 2000.P13 MEM Diemme® Filtration
The customer, a silver Mine in Mexico, had just started up a new 3500 t/d cyanidation plant to increase its silver bar production to 115 t/y.
The problems relevant to the adoption of this solution were:
• Environmental impact reduction, eliminating the tailing ponds.
Bilfinger Water Technologies exceeded the standard set by its competitors, and met all the customer’s needs, supplying a sludge dewatering plant comprising 3 filter presses Diemme® Filtration, model GHT 2000, able to dewater up to 4000 t/d of dry solids.
The residual cake moisture obtained is less than 20% and the sludge dewatering plant is able to recover and return up to 84% of water.
Previously, in 2008, the same mine bought 4 filter presses, model AUTOMAT 1500, from Bilfinger Water Technologies, employed in the Merril Crowe process.
