PASTE & FILTERED TAILINGS
Diemme ' s Domino up and running
The world ' s largest filter press is now in operation in Peru at Southern Copper Corp ' s Toquepala mine . IM found out the latest from Diemme Filtration
Diemme Filtration ’ s GHT5000F Domino , the largest filter press in the world , is finally in operation . The unit is running at the Toquepala copper mine in Peru , which is operated by Southern Copper Corporation ( SCC ), a majority owned subsidiary of Grupo Mexico .
The unit first arrived in Peru in the summer of 2022 followed by assembly , which Diemme says was done very quickly and efficiently , given that this was the first time for this record model . In tandem with this , SCC completed its works including the conveyor which delivers the tailings to the filter press .
Andrea Pezzi , Diemme Filtration Director Marketing and Communication told IM : “ We were then able to start the unit with the first couple of cycles in the second half of December 2022 . This was a big step – we were able to get the first filter cake produced . As of today the Diemme team is at the site , optimising the cycle and checking the instruments to bring it operation to a steady level before production begins to ramp up when we can fully test its capacity and performance .”
The main aim of SCC in installing the Domino is a gradual transition to dry stacked tailings at Toquepala . The first Domino is a pilot unit with the testing continuing over a period of about 12 months . The Domino with a filter plate size of 5 m x 5 m is capable of handling over 8,000 t / d . If the machine and the technology perform as expected , producing the targeted moisture levels at scale , SCC plans to install a much larger bank of up to 9 or 10 of these presses for a total capacity of over 80,000 t / d . The testing period will also allow SCC to get familiar with the machine operation and regular maintenance .
With a maximum total filtration volume of 71 m 3 , and a max total filtration area of 2,850 m 2 , the GHT5000F Domino remains the largest filter press available in the market . On large throughput projects , Diemme says the GHT5000F Domino will significantly improve the
