Filter cloths: Bluetes anti-abrasion resin

D. De Angelis, L.I. Balzaretti*, M. Motta, M. Reginato, Testori S.p.A., Italy

All over the world and across all industries, one of the most important challenges being faced is the development and implementation of technical solutions that could minimize total cost of ownership. Of particular interest, for what regarding the solid-liquid separation process, is the metal production & refining industry. Such industry is often characterized by the production of multiple compounds, different both in their chemical composition as well as in their economic value. Throughout the entire process, multiple intermediate products are transformed by means of a series of either pyro- or hydro-metallurgic refining steps. Filtration, whether solid-gas or solid-liquid separation, often plays a key role into the process. Generally speaking and independently of the input, at the end of each step a concentrate, with a variable content of a valuable metallic ion, is separated from tailings. Concentrates are to be efficiently segregated from the matrix they were originally present in and are further refined and processed until the desired purity level is achieved. Tailings can partially be recycled into the system to collect part of the concentrates that were not retained and broke through. Ultimately the tailing material needs to be disposed. The request for increased productivity leads to increased volumes of slurry to be filtered to separate concentrates....

.... the main purpose of the innovation proposed by Testori, named BlueTes, is to provide a solution which allows to overcome the drawbacks described above. The scope is to provide a filter cloth comprising reinforcing portions which do not have a significant local over-thickness and characterized by a high resistance to abrasion in various chemical environments....
