FILTRATION & THICKENING
Marketing and Communication told IM : “ This is one of the largest filtration plants of its kind in the gold sector and it is needed because there is simply no more space to deposit wet tailings there .”
In Brazil , Diemme has two interesting current projects - four units of GHT2500F-26 for an iron ore tailings application for 700 t / h . A second major current project in Brazil is in copper and has two streams - one for concentrates and one for tailings . One unit , an ME2000F , will process 20 t / h of copper concentrate . This is the largest in the ME range of filters , which are side beam models featuring fast opening and includes both rinsing and high pressure washing . These ME models are popular in the concentrates market . The tailings stream has three GHT2500F-26 processing about 450 t / h .
Moving up into the tailings filter press giant models , as things stand , two Diemme GHT5000F filter presses have been delivered - one to Southern Copper Corp ’ s Toquepala copper mine in Peru where it is being assessed for rollout of
The Diemme Filtration GHT5000F in-situ at Toquepala in Peru - the company is now offering an extended version with up to 191 plates
multiple units as part of tailings handling expansion ; this unit continues to run to required parameters and often exceeding them ; while unit two remains in Chile ready to be constructed , due to a delay in another copper project being built though it is expected to restart in the medium term . Plus Diemme is also working towards other options . Pezzi : “ While our largest unit remains the GHT5000F with 5x5 m plates we are also looking at boosting its capacity for some projects where we make it longer and increase the number of plates to 191 . This is a significant increase to our initial unit which had 141 plates for 8,000-10,000 t / d . The extended version is capable of 12,000-15,000 t / d plus . We are already offering this as an option . This is simply due to the fact that when you are talking about huge tonnages of tailings , you of course want to optimise the equipment as much as possible to reduce plant footprint and overall capital cost .”
A number of major mining company delegations have been to see the Toquepala unit and Pezzi said that discussions with some of these Tier 1 miners continue and that the momentum in terms of testing etc is building .
In terms of market strategy and approach , Pezzi said that some mining groups and
